Abbott Diagnostics CES 2026 brain injury blood test accuracy is drawing attention for a simple reason: it signals a shift from “wait-and-see” concussion assessment toward rapid, objective decision support at the point of care. At CES 2026, Abbott showcased its FDA-cleared i‑STAT TBI Plasma blood test, a handheld diagnostic designed to help clinicians evaluate mild traumatic brain injury (mTBI)—including concussions—in about 15 minutes, using blood biomarkers associated with brain tissue injury. That speed and portability create new clinical possibilities, but they also raise a new set of technical and operational questions: How do you integrate a near-real-time diagnostic into triage pathways, imaging workflows, EHR documentation, and quality reporting without creating new bottlenecks?

In this post, we’ll unpack what the test measures (and why), what “accuracy” really means in the current public evidence, and—crucially—how AI consulting and workflow automation (including n8n workflows) can help health systems operationalize rapid diagnostics safely and at scale.

Primary sources referenced throughout:

Abbott Diagnostics CES 2026 brain injury blood test accuracy: What’s new, and why it matters

Abbott’s i‑STAT TBI Plasma test is built for point-of-care (POC) use—think emergency departments, urgent care clinics, and potentially even sports sideline scenarios—where time, staffing, and imaging availability shape outcomes. The test is run on Abbott’s portable i‑STAT platform and is associated with the i‑STAT Alinity family of devices. Abbott notes the i‑STAT Alinity device is available outside the U.S. and not yet in the U.S., a detail that matters for deployment planning and international rollouts (SelectScience; Abbott newsroom).

What the test actually does

At a high level, the i‑STAT TBI Plasma test measures brain-injury-associated proteins that can enter the bloodstream after head trauma—specifically GFAP and UCH‑L1. These biomarkers are released from injured brain tissue and can rise after mTBI, enabling a faster, more objective assessment than symptom checklists alone (SelectScience; Abbott newsroom; Expert Review of Molecular Diagnostics).

Key operational claims (from the cited coverage):

  • Time to result: approximately 15 minutes (SelectScience; Abbott newsroom).
  • Time window: usable up to 24 hours post-injury (SelectScience; Abbott newsroom; Respiratory Therapy).
  • Sample type / access: Abbott has emphasized bedside access; importantly, FDA clearance for whole blood expands access beyond workflows that require lab processing of plasma/serum (Respiratory Therapy).

What it’s for (and what it’s not)

A central promise in Abbott’s positioning is triage support:

  • A negative result can help rule out the need for a head CT in certain clinical contexts, potentially reducing unnecessary imaging (Abbott newsroom; Respiratory Therapy).
  • A positive result is positioned as complementary to CT, supporting further evaluation rather than replacing imaging (Abbott newsroom; Respiratory Therapy).

This is a subtle but crucial technical distinction: the test is framed as a decision aid—especially valuable when clinical symptoms are ambiguous, CT access is constrained, or CT findings may be normal despite injury.

The clinical gap: Why “normal CT” doesn’t mean “no concussion”

One of the most compelling arguments for blood-based mTBI assessment is that CT imaging can look normal even when a patient has a clinically meaningful concussion. SelectScience notes that undetected concussions can occur in up to 5 in 10 cases, highlighting a persistent diagnostic ambiguity problem (SelectScience; Abbott media room).

This is where biomarkers are strategically powerful:

  • CT is excellent for detecting acute structural problems—bleeds, fractures, swelling patterns.
  • Concussion/mTBI often involves functional disruption and microstructural changes that may not present as clear CT findings.
  • Blood biomarkers (GFAP, UCH‑L1) add a biochemical lens—another signal channel for triage when imaging and symptoms don’t tell the full story.

In practice, healthcare teams juggle competing risks:

  • Missing a clinically significant brain injury.
  • Over-ordering CT scans (radiation exposure, cost, throughput constraints).
  • Overloading ED pathways during peak volume.

A fast, objective blood test can alter that calculus—but only if it’s integrated into workflow in a way that improves throughput and decision quality rather than adding friction.

How accurate is it—really? Interpreting “Abbott Diagnostics CES 2026 brain injury blood test accuracy”

A careful read of CES 2026 coverage and the linked references reveals an important nuance: public summaries do not consistently provide specific sensitivity/specificity percentages. The research and coverage describe the test as clinically useful and reliable, but they do not always disclose the numerical metrics within the cited CES articles (SelectScience; Abbott newsroom; Respiratory Therapy; HangryFeed).

So how should tech leaders and clinical operators interpret “accuracy” here?

Accuracy is not one number—especially for triage tools

For a triage-oriented diagnostic, the question is often:
How well does it help clinicians safely rule out the need for CT and identify patients who warrant further evaluation?

That framing emphasizes:

  • Negative predictive value (NPV) in the relevant population (to safely reduce CT utilization).
  • Clinical sensitivity for detecting injury patterns of concern.
  • Performance across time-from-injury, age groups, comorbidities, and pre-analytical variables (sample handling, device calibration, operator variability).

Evidence signals from TRACK‑TBI and biomarker research

The sources provided point to several evidence pillars:

  1. TRACK‑TBI (Lancet Neurology context)
    SelectScience and Abbott’s media room reference findings from the TRACK‑TBI initiative, described as one of the largest TBI studies, indicating that elevated GFAP detected by Abbott’s approach can help identify mild TBIs that may be missed by CT scans, supporting rapid triage (SelectScience; Abbott media room).
    This matters because it suggests the biomarkers are not just “correlated with injury,” but can add incremental signal where CT is less informative for mild cases.

  2. Biomarker kinetics (Expert Review of Molecular Diagnostics)
    The Expert Review of Molecular Diagnostics article notes that GFAP and UCH‑L1 rise significantly post‑TBI, supporting early detection (https://www.tandfonline.com/doi/abs/10.1080/14737159.2024.2306876).
    From a technical standpoint, biomarker kinetics influence:

  • When the test is most informative.
  • How to design protocols for repeat testing.
  • How to build decision support that respects time windows and pretest probability.
  1. Whole blood FDA clearance and access
    Respiratory Therapy highlights that FDA clearance for whole blood expands access beyond lab-processed workflows, enabling lab-quality results quickly (Respiratory Therapy).
    Operationally, whole blood capability can reduce:
  • Centrifugation steps.
  • Transport delays.
  • Lab backlog dependencies.
    It also introduces new QA considerations (operator training, cartridge supply chain, QC logging).

Abbott’s clinical positioning and expert development

SelectScience notes the test was developed by over 120 specialists and is positioned as a potential addition to standard-of-care alongside CT (SelectScience). Abbott’s Beth McQuiston, M.D. emphasizes the broader diagnostic paradigm shift: clinicians rely on blood tests for many organs, but “we haven’t had a blood test for the brain,” and this offers “an objective way to assess patients with concussions” (SelectScience; Respiratory Therapy).

The key takeaway: “Accuracy” here is best understood as clinically validated utility for decision-making—even if the CES coverage doesn’t publish a single headline metric.

The device and workflow reality: Point-of-care diagnostics are only as good as their integration

A 15-minute result only creates value if it arrives at the right moment in the care pathway and is captured reliably in systems of record.

Common integration pitfalls we see in digital health programs:

  • Results exist on-device but don’t reliably land in the EHR in time for disposition decisions.
  • Documentation becomes inconsistent (free text, scanned PDFs, or delayed entry).
  • Quality reporting and audit trails are incomplete.
  • Clinicians get alerts too late—or too often.
  • CT ordering patterns don’t change because decision pathways were not updated and operationalized.

This is where AI consulting and workflow automation can be decisive: not by “replacing clinicians,” but by building reliable orchestration around testing, routing, and documentation.

Where AI and automation can help—without turning triage into a black box

A brain injury triage workflow is not a single model prediction; it’s a coordinated system:

1) Workflow orchestration (n8n workflows for healthcare ops)

With n8n workflows, you can connect the POC testing event to downstream systems and stakeholders, such as:

  • EHR tasking (create a triage task for nursing/MD when a result posts).
  • Radiology order pathways (route for CT consideration when positive + symptoms criteria met).
  • Care coordination (auto-generate discharge instructions and follow-up scheduling when negative and clinically appropriate).
  • Quality and compliance (log timestamps: injury time, draw time, result time, disposition time).

Even when direct device integration is limited, n8n can orchestrate:

  • Secure inbox parsing (HL7/FHIR feeds when available).
  • Middleware APIs.
  • Human-in-the-loop confirmations (structured forms) to ensure traceability.

2) Clinical decision support that’s rules-first, AI-second

Given that public-facing coverage doesn’t provide a single “accuracy number,” a prudent approach is:

  • Start with evidence-aligned rules and institutional protocols.
  • Add AI where it improves consistency and reduces cognitive load (e.g., summarizing the record, extracting injury mechanism from notes, flagging anticoagulant use).

Examples of safe, high-value assistive automation:

  • A structured mTBI triage checklist auto-populated from the chart (meds, age, prior TBI, anticoagulant/antiplatelet use).
  • A “next best action” panel that explains why a recommendation is made (transparent criteria, not opaque scores).
  • Automated patient instructions tailored to test result + symptoms + return-to-play/return-to-work guidance.

3) Throughput analytics and continuous improvement

Once a rapid test is introduced, leaders will want to know:

  • Did CT utilization change?
  • Did ED length-of-stay improve?
  • Were there return visits or missed injuries?
  • Are results available within the intended 15-minute window in real operations?

Automation can continuously collect timestamps and operational metadata, enabling:

  • Dashboards for bottleneck detection.
  • Drift monitoring (e.g., longer turnaround during certain shifts).
  • Protocol adherence reporting.

Practical takeaways for tech professionals, developers, and innovators

For developers building around POC diagnostics

  1. Design for time sensitivity. A “15-minute test” fails if integration takes 2 hours. Optimize event-driven delivery and prioritize result visibility in the clinician’s workflow.
  2. Treat provenance as a first-class feature. Capture device ID, operator ID, specimen type (whole blood vs plasma), and timestamps.
  3. Implement human-in-the-loop checkpoints. Especially early, build confirmations for critical workflow steps (e.g., CT order cancellation based on negative result should require protocol-based signoff).
  4. Plan for variability. Connectivity outages, cartridge stockouts, QC holds—these are normal. Your automation should degrade gracefully.

For tech leaders and innovators in hospitals/health systems

  1. Update the pathway, not just the toolset. A new diagnostic doesn’t change outcomes unless triage, imaging, and discharge processes are redesigned around it.
  2. Use automation to reduce documentation burden. If clinicians must re-enter results manually, adoption and consistency will suffer.
  3. Measure what matters. Track CT rates, ED throughput, patient outcomes, and operational KPIs—not just number of tests run.
  4. Be explicit about scope. This test is positioned to complement CT and assist triage, not to replace imaging across the board (Abbott newsroom; Respiratory Therapy).

For AI governance and compliance stakeholders

  1. Prefer interpretable decision support for high-stakes triage. Keep protocols clear and auditable.
  2. Log everything. If an automated workflow influences imaging decisions, you need robust audit trails.
  3. Validate locally. Even FDA-cleared tools must be implemented with local clinical governance, training, and monitoring.

Why this matters beyond TBI: The broader technical implication

Abbott’s CES 2026 showcase underscores a larger shift: diagnostics are becoming distributed computing nodes—portable, fast, and increasingly data-rich. As more tests move to the bedside, the limiting factor becomes less about assay chemistry and more about:

  • interoperability,
  • workflow design,
  • data governance,
  • and operational analytics.

In other words: the future of healthcare diagnostics is as much a systems integration problem as it is a biomedical one.

How our AI consulting and n8n workflow automation services help teams operationalize rapid diagnostics

Our work sits at the intersection of AI, automation, and real-world process constraints. For organizations adopting point-of-care diagnostics like Abbott’s i‑STAT TBI Plasma test, we typically help with:

  • Workflow discovery and pathway redesign: mapping current-state triage → imaging → discharge, identifying where a 15-minute result should change decisions.
  • n8n workflow automation: orchestrating results routing, notifications, documentation tasks, follow-up scheduling, and KPI capture.
  • Integration strategy: aligning device/middleware feeds with EHR workflows, and implementing fallback processes when direct integration isn’t available.
  • Decision support implementation: building rules-based and AI-assisted tools that are transparent, auditable, and clinically governed.
  • Monitoring and continuous improvement: dashboards, alert tuning, and operational QA to ensure the new workflow performs under real conditions.

Closing: Turning a rapid TBI blood test into measurable clinical and operational value

Abbott Diagnostics CES 2026 brain injury blood test accuracy isn’t just a headline—it’s a preview of how care delivery is changing: faster diagnostics, closer to the patient, with decision impact in minutes rather than hours. The i‑STAT TBI Plasma test’s ability to measure GFAP and UCH‑L1, deliver results in about 15 minutes, and support CT triage decisions—potentially even when CT appears normal—marks a meaningful step toward more objective mTBI assessment (SelectScience; Abbott newsroom; Respiratory Therapy; Expert Review of Molecular Diagnostics).

But the organizations that benefit most won’t be the ones that simply purchase the device. They’ll be the ones that instrument the workflow, automate the handoffs, and build governance-grade decision support around it.

Additional Insights: Abbott handheld brain injury diagnostic accuracy CES 2026: What the i-STAT TBI means for faster triage—and smarter healthcare automation

The headline from CES 2026 wasn’t just another wearable or AI demo—it was a clinical workflow shift. Abbott handheld brain injury diagnostic accuracy CES 2026 became a top talking point after Abbott showcased its i-STAT TBI handheld diagnostic device (Jan 6–9, Las Vegas), demonstrating how a 15-minute point-of-care blood test can improve decision-making for mild traumatic brain injury (mTBI) and concussion. The device measures brain injury biomarkers—glial fibrillary acidic protein (GFAP) and ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1)—and returns results at the bedside to help clinicians decide whether a CT scan is needed or if a patient may be safely discharged.
Sources:

This matters for two reasons. First, it pushes brain injury assessment toward an objective, scalable signal—like lab tests did for heart and kidney conditions—addressing the reality that CT can miss subtle injuries and symptom-based evaluations can be inconsistent. Second, it creates a new automation surface area: rapid diagnostics + clinical decision support + downstream workflow automation (orders, referrals, discharge instructions, insurance, follow-up). For AI consulting teams and workflow automation builders (including those using n8n workflows), this is the kind of innovation that can meaningfully reduce operational friction while improving care consistency.

Abbott handheld brain injury diagnostic accuracy CES 2026: the i-STAT TBI in plain terms

At CES 2026, Abbott highlighted the i-STAT TBI at Booth #8713 (LVCC North Hall) with interactive demos focused on brain health diagnostics, faster triage, and workflow modernization.
Sources:

What the device does (and what changed recently)

The i-STAT TBI cartridge performs a quantitative biomarker test from a few drops of blood placed into a single-use cartridge, analyzed on the handheld i-STAT platform at the bedside. Importantly, the cartridge is now FDA-cleared for whole blood (previously plasma/serum), which reduces handling steps and makes true point-of-care use more practical in emergency departments, urgent care, and potentially non-hospital settings. The reader displays results with interpretation to guide next steps—particularly whether to proceed with imaging (CT) or consider discharge with appropriate instructions.
Sources:

Why biomarkers like GFAP and UCH-L1?

GFAP and UCH-L1 are proteins associated with brain cell injury. In acute brain trauma, these biomarkers can rise in blood, offering an objective physiological correlate to what is otherwise a complex diagnostic domain. This is especially relevant in mTBI, where symptoms (headache, dizziness, confusion) can overlap with dehydration, stress, intoxication, or pre-existing conditions—and where imaging doesn’t always reveal subtle injury. Abbott’s positioning is essentially: bring a “blood test moment” to brain assessment, similar to how troponin changed chest-pain workups.

The “why now” problem: scale and underdiagnosis

Concussions and mild TBIs are common and frequently underdiagnosed. Abbott and related coverage cite an estimate of ~69 million TBIs worldwide annually—a scale that makes “gold-standard imaging for everyone” unrealistic, expensive, and in many cases clinically unnecessary. A fast rule-out test changes the economics and throughput dynamics of frontline care.
Sources:

What the accuracy data actually says (and how to interpret it responsibly)

When people hear “high accuracy,” they often think it means “it’s great at confirming injury.” But the most operationally meaningful metric for ED triage is often the ability to rule out significant injury safely.

Evidence point #1: TRACK-TBI and biomarker signal beyond CT

A TRACK-TBI study (2019, Lancet Neurology) is referenced in Abbott’s materials: 64% of patients with the highest GFAP levels had brain injury confirmed on MRI even when CT was normal. That’s significant because it frames biomarkers as a signal that can correlate with injury that CT may not detect—supporting the broader premise that “CT-negative” isn’t always “injury-negative.”
Source: https://www.multivu.com/players/English/8593251-abbott-traumatic-brain-injury-test/

Evidence point #2: Rapid i-STAT-based GFAP/UCH-L1 performance against CT findings

A peer-reviewed paper (available on PubMed Central) reported that a rapid i-STAT-based GFAP/UCH-L1 test showed:

  • Sensitivity: 0.958 (95% CI: 0.906–0.982)
  • Negative Predictive Value (NPV): 0.993 (95% CI: 0.985–0.997)
    for acute traumatic intracranial injury on head CT, within 12 hours of injury.
    However:
  • Specificity was lower: 0.404
  • Positive Predictive Value (PPV): 0.098 (limited, and comparable to lab platforms)

In practical terms: the test is exceptionally strong at saying “this patient is very unlikely to have an acute intracranial injury visible on CT,” but a positive result does not strongly confirm CT-positive injury—so you use it to reduce unnecessary CTs, not to definitively “diagnose” every positive as CT-confirmable trauma.
Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC9290667/

Why high NPV is such a workflow unlock

In an ED setting, a test with NPV ~0.993 can support a protocol where low-risk patients with negative biomarker results avoid imaging, reducing:

  • radiation exposure
  • CT bottlenecks
  • cost and payer friction
  • length of stay
  • clinician cognitive load in over-triage scenarios

The study explicitly supports the potential to cut CT use in ED mTBI pathways.

CES 2026 positioning: beyond hospitals, toward distributed care

Abbott and third-party coverage describe i-STAT TBI as a potential “game-changer” not only in emergency departments, but also in sports sidelines and urgent care, where real-time decisions (rest, observation, referral) need objective support.
Sources:

At CES, Abbott also ran sessions like “Next-Gen Diagnostics: A New Era of Early Detection” (Jan. 8, 9 a.m.) and other programming on biowearables and sensors, signaling a broader narrative: early detection plus connected workflows.
Source: https://www.abbott.com/en-us/abbott-at-ces

This is where technology leaders should pay attention. The clinical innovation is the biomarker cartridge—but the system innovation is what happens when rapid diagnostics become routine, decentralized, and integrated.

Development depth: why this isn’t a “quick gadget,” and why that matters for buyers

According to Abbott’s materials and coverage, the test was developed over 7 years by 300+ scientists, and it has achieved FDA clearance as well as CE marking. Those milestones matter not just clinically, but operationally: regulated devices with clear intended use and validated performance are the only ones that can be credibly wired into enterprise care pathways, payer documentation, and quality reporting.
Sources:

Experts also frame the device as filling a long-standing gap: brain injury assessment has lacked the kind of common, objective blood tests available for other organs—leading to variability and over-reliance on subjective evaluation.
Sources:

Clinically, the promise is earlier, better decisions—rest protocols, observation, rehab referral—to reduce secondary injury risk and improve outcomes. Operationally, the promise is standardized triage in high-variance environments.

The technical implications: “diagnostic-to-decision pipelines” are the new frontier

From a technology strategy viewpoint, i-STAT TBI is part of a broader shift: diagnostic devices are becoming event producers in a real-time system. The value doesn’t end at the numeric GFAP/UCH-L1 readout; it expands when that readout triggers the right next actions.

Think in terms of an event-driven architecture

A mature implementation treats a bedside test result as a structured event:

  • Patient context: age, injury time, mechanism, medications, anticoagulants, symptoms
  • Test metadata: device ID, lot number, time to result, operator ID, QC status
  • Result payload: numeric values + interpreted flag (e.g., below/above threshold)
  • Downstream actions: CT order suggestion, discharge pathway, observation order set, follow-up scheduling

To make that real, organizations need integration work: LIS/EHR connectivity, message normalization, policy mapping, and governance.

AI’s role: decision support, not “auto-diagnosis”

Given the test’s lower specificity and PPV, AI should not be positioned as “confirming brain injury.” Where AI does help:

  • Protocol adherence: ensure the right pathway is applied for the right cohort (e.g., time since injury within the validated window)
  • Risk stratification: combine biomarker result with clinical features to prioritize imaging and observation resources
  • Documentation automation: produce consistent notes, discharge instructions, and follow-up plans aligned with policy
  • Population analytics: detect site-to-site variation, bias, and drift in utilization and outcomes

This is the practical posture: AI as orchestration and decision support across a regulated pathway.

Where n8n workflows fit: automating the “last mile” around point-of-care diagnostics

Many healthcare teams underestimate how much time is lost after a result appears. Even when clinicians can act quickly, the organization often can’t: communication steps, follow-ups, billing codes, care navigation, and reporting are still manual.

This is where n8n workflows (and similar automation platforms) become powerful—especially when paired with an AI consulting approach that respects compliance, auditability, and clinical governance.

Example workflow patterns (high impact, low hype)

1) Result-to-triage routing (ED / urgent care)

  • Trigger: i-STAT TBI result posted (or entered)
  • n8n actions:
    • Create/route task in the EHR work queue (or a secure ops tool)
    • Notify clinician channel with structured context (not raw PHI in insecure tools)
    • Append recommended order set link based on policy

2) CT utilization reduction program (quality + operations)

  • Trigger: negative biomarker result + CT order placed
  • n8n actions:
    • Flag for retrospective review (quality nurse queue)
    • Collect contextual fields for audit (injury time, anticoagulants, neuro deficits)
    • Generate monthly dashboards (de-identified aggregates)

This aligns with the published implication that the test may reduce CT usage—if organizations operationalize it with governance and feedback loops.
Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC9290667/

3) Discharge automation and follow-up safety net

  • Trigger: negative result + discharge decision
  • n8n actions:
    • Auto-generate patient-specific discharge instructions (concussion red flags, rest guidance)
    • Schedule follow-up call/televisit
    • Send secure reminders and symptom check-ins
    • Escalate if symptoms worsen (rule-based triage to nurse line)

4) Sports and distributed care scenarios
Coverage points to sidelines and urgent care as key expansion areas. These are high-variability environments where automation can enforce consistency: capture injury time, log symptoms, store consent, and coordinate referral.
Sources:

Challenges and constraints leaders should plan for

A device can be excellent and still fail to deliver ROI if the surrounding system is not designed.

1) Specificity and false positives: operational consequences

With specificity reported around 0.404, many positives won’t correspond to CT-positive findings. If teams interpret “positive” as “definitely injured,” they can inadvertently increase imaging, observation, and anxiety. The correct operational framing is rule-out, not rule-in.
Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC9290667/

2) Timing windows and protocol fidelity

The cited performance is for patients tested within 12 hours post-injury. Workflow automation must enforce timing constraints (e.g., prevent misapplication outside validated windows) and document exceptions.

3) Integration, identity matching, and audit trails

Point-of-care devices introduce classic integration risks: wrong patient selection, duplicate records, missing operator IDs, or results that don’t map cleanly into the EHR. Automated workflows should include:

  • patient identity verification steps
  • QC checks and exception routing
  • immutable logs for compliance and incident investigation

4) Governance: who owns the pathway?

Rolling out a rapid test touches ED leadership, radiology, lab, nursing, compliance, and IT. Successful teams treat this as a product rollout with clear owners, not “just another instrument.”

Practical takeaways (for developers, tech leaders, and innovators)

  1. Design for NPV-driven pathways. The headline metric to build around is the negative predictive value (0.993)—this is what enables safe CT reduction strategies when clinically appropriate.
    Source: https://pmc.ncbi.nlm.nih.gov/articles/PMC9290667/

  2. Build “result → decision → documentation” as one pipeline. The device returns results in ~15 minutes; your operations should too. Automate order sets, discharge templates, and follow-up scheduling to prevent the result from becoming an isolated data point.
    Sources:

  1. Treat distributed settings as first-class citizens. If urgent care and sports sidelines are part of the adoption story, invest early in secure mobile workflows, identity matching, consent capture, and referral routing.
    Sources:

  1. Instrument everything for continuous improvement. Track CT rate, length of stay, 72-hour returns, and pathway compliance. Use automation to generate de-identified aggregates for leaders and quality teams.

  2. Use AI where it’s strongest: policy adherence and summarization. Don’t oversell “AI diagnosis.” Use AI to summarize encounters, enforce protocol constraints (like time since injury), and reduce clinician admin burden with reviewable outputs.

How this connects to our AI consulting and automation services

Innovations like Abbott’s i-STAT TBI succeed when organizations connect diagnostics to action—securely, compliantly, and measurably. That’s where our team typically engages:

  • AI consulting for clinical workflow design: translating test performance characteristics (high sensitivity/NPV, lower specificity) into safe, operational protocols and decision support
  • n8n workflow automation: building event-driven automations around results—triage routing, documentation generation, follow-up coordination, quality reporting, and exception handling
  • Integration strategy: aligning device outputs with EHR/LIS realities, creating audit trails, and reducing manual handoffs that slow care

CES 2026 made it clear that diagnostics are becoming faster and more decentralized (Abbott’s booth demos and programming leaned heavily into this future). The competitive differentiator for providers and innovators won’t be access to a single device—it will be the ability to operationalize it across sites with consistent outcomes.

Additional Insights: Abbott Diagnostics CES 2026 brain injury blood test accuracy: What the i-STAT TBI Plasma means for faster triage—and smarter healthcare automation

When people search for “Abbott Diagnostics CES 2026 brain injury blood test accuracy”, they’re really asking a bigger question: Are we finally at the point where a fast, reliable blood test can change how we triage concussions and mild traumatic brain injury (mTBI)—and can health systems operationalize that change at scale?

At CES 2026, Abbott Diagnostics showcased its FDA-cleared i-STAT TBI Plasma test, a handheld diagnostic designed to deliver rapid results to support assessment of mild traumatic brain injuries and concussions (sources: https://www.hangryfeed.com/insights/posts/abbott-brain-injury-test-20262026-04-05, https://www.hangryfeed.com/insights/posts/abbott-diagnostics-ces-2026-brain-injury-detection-accuracy-what-the-i-stat-tbi-plasma-test-means-for-faster-triage-and-smarter-healthcare-automation). The device produces results in about 15 minutes by measuring two blood biomarkers—GFAP and UCH-L1—that are released following head trauma (sources: https://www.orlandohealth.com/content-hub/orlando-health-first-in-the-world-to-use-abbotts-new-blood-test-for-traumatic-brain-injuries, https://www.abbott.com/en-us/corpnewsroom/products-and-innovation/finally-a-blood-test-for-traumatic-brain-injury).

That single shift—from “wait, observe, maybe image” to “test, stratify, act”—has massive implications not only for emergency medicine, sports medicine, and first responders, but also for workflow automation and AI consulting. A 15-minute diagnostic is only as transformative as the operational pathway that receives it, records it, routes it, and uses it to trigger the next best action.

Below, we’ll break down what this test does, what “accuracy” means in practice, why it closes a longstanding diagnostic gap, and how healthcare organizations can build automated, auditable workflows (including n8n workflows) around it to accelerate triage while improving governance and patient experience.

Abbott Diagnostics CES 2026 brain injury blood test accuracy: What’s new and why it matters

Abbott’s i-STAT TBI Plasma test is positioned for a very specific clinical problem: quickly assessing suspected mTBI/concussion in a way that can meaningfully influence whether a patient needs a head CT.

The core innovation: rapid biomarker-based assessment in a handheld format

The i-STAT TBI Plasma test produces results in ~15 minutes and measures two biomarkers:

  • GFAP (Glial Fibrillary Acidic Protein)
  • UCH-L1 (Ubiquitin C-terminal Hydrolase L1)

These proteins are released into the bloodstream when brain cells are damaged during head trauma; higher concentrations correlate with more severe injury (source: https://www.orlandohealth.com/content-hub/orlando-health-first-in-the-world-to-use-abbotts-new-blood-test-for-traumatic-brain-injuries). The test’s promise is speed and practicality—supporting decision-making while the patient is still in initial triage instead of after prolonged observation or delayed imaging.

This is not a “diagnose everything” blood test. It’s designed to improve the triage decision—especially around when CT is (or isn’t) necessary—while offering another signal when CT is inconclusive or appears normal.

What “accuracy” means here: clinical utility, not just a single metric

It’s tempting to reduce “accuracy” to a single percentage. In real-world emergency care, accuracy is often better understood as clinical utility—whether a test changes decisions safely and measurably.

Abbott and partner sites emphasize three practical uses (sources: https://www.orlandohealth.com/content-hub/orlando-health-first-in-the-world-to-use-abbotts-new-blood-test-for-traumatic-brain-injuries, https://www.abbott.com/en-us/corpnewsroom/products-and-innovation/finally-a-blood-test-for-traumatic-brain-injury):

  1. Negative result → rule out the need for a head CT scan
    This is a crucial operational outcome. CT is expensive, time-consuming, and contributes to radiation exposure. A reliable “rule-out” pathway can reduce unnecessary imaging, shorten length-of-stay, and free radiology capacity.

  2. Positive result → complements CT to help evaluate whether a TBI has occurred
    A positive biomarker signal doesn’t replace imaging; it adds context. Clinicians still evaluate symptoms, risk factors, and imaging findings. But the biomarker provides an additional objective data point—especially helpful when symptoms are ambiguous.

  3. Results within 24 hours of trauma can help determine if further imaging is unnecessary
    Timing matters. The test is framed for use in the window where triage decisions are made and where avoiding unnecessary imaging can reduce burden on patients and systems.

The major gap it targets: “normal CT” doesn’t always mean “no injury”

According to reporting on research published in Lancet Neurology through the TRACK-TBI study, this type of diagnostic blood testing can detect mild traumatic brain injuries even when a CT scan appears normal (source: https://www.selectscience.net/article/new-diagnostic-blood-test-could-help-rapidly-detect-brain-injury-even-if-ct-scan-is-normal).

That’s a critical point in the “accuracy” discussion: CT is great at detecting certain acute structural injuries that require urgent intervention, but it may not capture the full spectrum of mTBI. If clinicians only have symptoms + CT, a meaningful subset of patients may be misclassified.

Abbott also cites that approximately 5 out of 10 concussions currently go undetected (source: https://www.abbott.com/en-us/corpnewsroom/products-and-innovation/finally-a-blood-test-for-traumatic-brain-injury). A test that improves detection—especially when imaging is normal—changes follow-up care, return-to-work/return-to-play decisions, and patient counseling.

Development and adoption: a 20+ year arc from research to protocolized care

This is not an “overnight CES gadget.” The i-STAT TBI Plasma test was developed by Abbott in collaboration with the Department of Defense, building on more than 20 years of pioneering research by Dr. Linda Papa and others (source: https://www.orlandohealth.com/content-hub/orlando-health-first-in-the-world-to-use-abbotts-new-blood-test-for-traumatic-brain-injuries). That origin story matters because DoD-driven clinical needs—battlefield injuries, blunt trauma, rapid triage—often push innovation in diagnostics and logistics.

On the adoption side:

These are important signals: hospitals aren’t just piloting the test—they’re integrating it into protocols, which means defined decision trees, defined responsibilities, and repeatable operations. That’s where automation and AI can drive the next order of magnitude in impact.

The operational reality: a 15-minute test can still create a 2-hour bottleneck

Even with a rapid assay, many organizations struggle with:

  • Ordering and documentation friction in the EHR
  • Manual handoffs between ED staff, lab processes, and radiology
  • Delays in notifying clinicians of results
  • Inconsistent criteria for CT avoidance or escalation
  • Lack of structured data for downstream analytics and quality improvement

This is exactly where workflow automation—done safely and compliantly—turns a diagnostic innovation into a system-level capability.

A common pattern we see in digital transformation is this: the technology exists, but the workflow remains analog. The result is “local efficiency” (the test is fast) without “end-to-end efficiency” (the patient journey is still slow).

How to automate around i-STAT TBI Plasma: a practical workflow blueprint (with n8n)

At our company, we help teams design AI-enabled process automation and implement n8n workflows that connect clinical systems, operational tools, and analytics stacks. Below is an example blueprint you can adapt—whether you’re a hospital innovation team, a digital health vendor, or an enterprise IT group supporting clinical operations.

1) Capture structured context at intake (without slowing triage)

Goal: Make the lab result immediately actionable by pairing it with context.

Data to capture (structured):

  • Injury timestamp (for “within 24 hours” criteria)
  • Mechanism of injury (fall, sports, MVC)
  • Symptoms checklist
  • Red flag criteria (per protocol)
  • Patient risk factors (anticoagulants, age, previous TBI)

Automation idea:
Use an intake form (or EHR embedded flowsheet) that writes discrete fields. n8n can validate completeness and route exceptions (e.g., missing time-of-injury) to a triage coordinator queue.

2) Orchestrate “order → result → next action” as an event-driven workflow

Goal: When results arrive, trigger the next step automatically.

Example event triggers:

  • New i-STAT TBI Plasma result posted
  • Result value crosses protocol threshold (negative vs positive)
  • Time since injury window validated

n8n workflow concept:

  • Trigger: HL7/FHIR message webhook (or integration layer event)
  • Node: Rules engine (protocol mapping)
  • Node: Create/Update task in clinical task manager (or EHR inbox)
  • Node: Notify care team via secure messaging
  • Node: Log decision + rationale for audit trail

Even if you can’t directly integrate the device feed on day one, you can still automate downstream steps by pulling results from a lab system API or even controlled document parsing (with strict validation).

3) Build a “CT stewardship” pathway that’s measurable

Goal: Reduce unnecessary CT scans safely—and prove it.

Automations to add:

  • If negative and no red flags: suggest “CT not indicated” pathway + observation instructions
  • If positive or red flags: route to imaging order set + neuro consult criteria
  • If CT performed: record whether biomarkers were positive/negative for later analysis

This creates a closed-loop pathway where you can measure:

  • CT ordering rate pre/post adoption
  • ED length-of-stay impact
  • 72-hour return visits
  • Adverse events
  • Protocol adherence by shift/site

4) Use AI carefully: decision support, not autonomous diagnosis

Goal: Assist clinicians and ops teams without overstepping clinical responsibility.

Appropriate AI use cases here include:

  • Summarizing the triage note + lab result + risk factors into a standardized handoff
  • Flagging missing documentation needed for protocol compliance
  • Identifying patterns: which cohorts still get CT despite negative tests, and why
  • Forecasting demand: when staffing or imaging capacity will be constrained

If you’re deploying AI in healthcare workflows, governance is the product. That includes logging, versioning prompts/models, and ensuring that recommendations are transparent and reviewable.

Technical implications: diagnostics are becoming data products

CES 2026 is often framed as consumer tech, but Abbott’s presence underscores a broader shift: diagnostics are increasingly computational, connected, and workflow-native.

Here are the deeper technical implications for tech leaders:

  1. Edge diagnostics + rapid turnaround compress decision time
    If results land in 15 minutes, your systems must route tasks and guidance in minutes—not hours. That requires event-driven architecture, robust integration, and resilient messaging.

  2. Biomarkers expand the observable state space
    Symptom-based triage is noisy. Adding GFAP/UCH-L1 creates new features for clinical reasoning and analytics. Over time, that can enable better stratification models—if data is captured cleanly.

  3. Protocolized care becomes automatable care
    WVU’s adoption “as part of a care protocol” (source: https://wvumedicine.org/news-feed/news-article/WVU-Medicine/Front-Page/wvu-rockefeller-neuroscience-institute-leads-country-in-adoption-of-brain-injury-test-care-protocol/) is the key phrase. Protocols are executable. Executable protocols can be encoded into workflow engines—reducing variability while preserving clinician oversight.

  4. Interoperability becomes the differentiator
    The test itself may be FDA-cleared, but competitive advantage for providers will come from how well they integrate it into EHRs, secure messaging, patient instructions, quality reporting, and population health insights.

Practical takeaways for developers, IT leaders, and innovators

  1. Design for “result-to-action time,” not just test time
    Measure: time from result availability → clinician acknowledgement → decision → discharge/imaging. That’s where bottlenecks hide.

  2. Treat “negative vs positive” as workflow branches with guardrails
    Build a rules layer that is:

    • Versioned (protocol updates happen)
    • Auditable (why a recommendation was made)
    • Testable (simulation against historical cases)

  3. Start with automation that reduces clerical load
    Low-risk, high-impact automations:

    • Auto-create follow-up tasks for concussion instructions
    • Auto-generate structured discharge education based on result + symptoms
    • Auto-route cases to case management when needed

  4. Instrument everything for quality improvement
    The value of this diagnostic grows when you can prove outcomes:

  5. Plan governance early: clinical, technical, and compliance
    Especially with AI in the loop, define:

    • Who owns protocol logic
    • Who approves workflow changes
    • What gets logged
    • How exceptions are handled (e.g., conflicting signals)

Where our AI consulting and n8n workflow expertise fits

Healthcare teams don’t need more dashboards—they need reliable automation that respects clinical realities.

Our work typically includes:

  • AI consulting to define safe, high-ROI clinical and operational use cases
  • n8n workflow automation to orchestrate events across lab systems, EHR integrations, secure communications, ticketing, and analytics
  • Data engineering patterns that transform diagnostic signals into actionable, auditable workflows
  • Governance-by-design: logging, monitoring, access control, and protocol versioning

If you’re evaluating how to operationalize rapid diagnostics like Abbott’s i-STAT TBI Plasma—whether in an ED, a sports medicine program, or a first responder protocol—we can help you move from “we have the test” to “we have an end-to-end system.”

Closing: a diagnostic breakthrough is only half the story

But the organizations that realize the biggest benefit will be those that implement the surrounding system: event-driven integration, protocol automation, measurable CT stewardship, and careful AI decision support.

Additional Insights: Abbott Diagnostics CES 2026 brain injury detection accuracy: What the i-STAT TBI Plasma test means for faster triage—and smarter healthcare automation

The phrase “Abbott Diagnostics CES 2026 brain injury detection accuracy” has been trending for good reason: at CES 2026, Abbott Diagnostics spotlighted an FDA-cleared, handheld blood test that can help detect mild traumatic brain injury (mTBI)—including concussions—in about 15 minutes using just a few drops of blood. Instead of relying solely on symptom checklists and imaging availability, clinicians can measure brain-injury-associated proteins at picogram levels, bringing lab-grade biomarker insight closer to the bedside and the field.

Abbott’s approach—centered on the i-STAT TBI Plasma test—has implications well beyond emergency medicine. It’s a signal of where diagnostics is heading: portable point-of-care testing, higher-frequency decision points, and real-time clinical workflows that increasingly depend on AI, automation, and integration to be usable at scale. In this post, we’ll break down what Abbott showed, what the published evidence says about accuracy and clinical impact, and how healthcare organizations can operationalize these results using modern automation stacks (including n8n workflows) to improve triage, documentation, and follow-up.

Abbott Diagnostics CES 2026 brain injury detection accuracy: what was actually shown?

At CES 2026, Abbott Diagnostics showcased its FDA-cleared i-STAT TBI Plasma blood test, a handheld diagnostic that can deliver results in roughly 15 minutes. The test uses a small blood sample (a few drops) to measure brain injury-related proteins—most notably GFAP (glial fibrillary acidic protein) and UCH-L1 (ubiquitin C-terminal hydrolase L1)—at extremely low concentrations (reported as picogram-level detection). This positions the test as a rapid way to support identification of mTBI and to help guide downstream decisions like whether a CT scan is necessary.

Sources:

Importantly, CES coverage emphasized speed, portability, and precision versus traditional assessment methods—particularly in time-sensitive environments where clinical observation, self-reported symptoms, and imaging access can be inconsistent. Abbott’s Medical Director Beth McQuiston, MD highlighted the device during a Sage panel on AI-powered diagnostics, underscoring the value of point-of-care decision support in modern care delivery.

A note on “accuracy” numbers from CES 2026

If you’re searching for CES demo-specific sensitivity/specificity percentages: public sources do not report exact numerical sensitivity/specificity figures tied specifically to the CES 2026 demonstrations. The performance claims and clinical validity discussed in media coverage trace back to prior studies (e.g., TRACK-TBI) and FDA-cleared data, largely published across 2019–2021. That distinction matters for anyone building procurement, clinical, or regulatory narratives: CES 2026 was a visibility moment, not the release of a new performance dataset.

Sources:

How the i-STAT TBI Plasma test works (in practical technical terms)

Traditional concussion evaluation often hinges on clinical signs, reported symptoms, and imaging (CT) when warranted. But mTBI can be subtle, and CT scans are designed to detect certain types of structural injury—not every physiologic disruption. Abbott’s approach leverages blood-based biomarkers that increase when brain cells or supporting structures are injured.

The biomarkers: GFAP and UCH-L1

  • GFAP is associated with astroglial injury (support cells in the central nervous system).
  • UCH-L1 is associated with neuronal cell body injury.

Abbott’s i-STAT TBI Plasma test measures these biomarkers quickly and at very low concentrations (picogram levels)—a key technical enabler for early detection, given that biomarker levels may be small and time-sensitive after injury.

Sources:

Point-of-care architecture: speed changes the workflow

In diagnostics, “accuracy” is only half the story. The other half is time-to-result and where the result is produced. A 15-minute handheld test can be used:

  • in emergency departments during triage,
  • in urgent care settings,
  • potentially in resource-limited environments where CT access is constrained,
  • and in operational contexts like military medicine (notably relevant here).

Abbott notes that this blood test technology was co-developed with the Department of Defense, a detail that highlights the priority on portability and rapid decision-making in high-stakes environments.

Sources:

What the research says about accuracy and clinical value

1) “Superior sensitivity to CT scans” in specific contexts: TRACK-TBI insights

One of the most cited findings comes from the TRACK-TBI study (reported as 450 patients in coverage). The key takeaway: elevated GFAP levels detected brain injury in patients with negative CT scans more sensitively than other biomarkers such as UCH-L1, S100B, or NSE, identifying cases that CT missed.

This is not a claim that CT is obsolete—CT is essential for detecting acute intracranial bleeding and other structural injuries. Rather, the implication is that CT can be normal while biologic signals of brain injury are present, and GFAP appears particularly useful for capturing that signal in the studied cohort.

Sources:

Why that matters operationally:
If a biomarker test can reliably flag higher-risk cases even when CT is negative, it may change how clinicians approach:

  • observation vs discharge decisions,
  • follow-up scheduling,
  • return-to-play/work guidance,
  • and escalation criteria when symptoms evolve.

2) Negative-result reliability and CT reduction potential

Abbott reports that a “Not Elevated” result on the dual-biomarker assay (GFAP and UCH-L1) correlates with the absence of acute traumatic intracranial lesions on CT. In the pivotal study referenced in Abbott materials, 40.4% of negative results were true negatives, and the test could potentially reduce unnecessary CT scans by up to 40%.

This is one of the most business-relevant claims, because CT scanning involves:

  • cost,
  • ED throughput constraints,
  • radiation exposure considerations,
  • and downstream operational burden.

Even a partial reduction in unnecessary CT utilization can improve patient flow and reduce strain—if implemented with appropriate clinical governance and safety protocols.

Sources:

3) Prognostic accuracy: predicting longer-term outcomes

Beyond immediate triage, Abbott-associated biomarker research points toward prognostic value:

  • GFAP predicted 6-month death with 87% probability and severe disability with 86%.
  • UCH-L1 predicted death with 89% probability and disability with 86%.
  • The highest 20% of biomarker levels indicated the greatest risk, with risk concentrated mostly within the first month.

These findings suggest a possible future in which biomarker levels don’t just answer “Do we need a CT?” but help stratify patients into follow-up pathways—neurology referrals, cognitive monitoring, rehab check-ins, or digital therapeutics.

Source:

It’s also important to be precise: coverage notes that additional studies are needed for prognostic refinements. Prognostic modeling is notoriously sensitive to cohort selection, timing of blood draw, comorbidities, and care variability—so responsible deployment should treat prognostic outputs as decision support, not deterministic predictions.

Source:

4) Point-of-care performance and the “undetected concussion” gap

The CES 2026 narrative also emphasized a real-world gap: concussions are frequently missed by traditional methods—reported as 5 out of 10 going undetected in some contexts—making a strong case for objective, rapid tools at the point of care. Abbott’s i-STAT platform provides bedside results, and Abbott notes that i-STAT Alinity is available outside the U.S., highlighting global deployment considerations.

Sources:

Why CES 2026 matters: diagnostics is becoming a software-and-workflow problem

CES is no longer just consumer gadgets—it’s a preview of where connected devices, AI-powered diagnostics, and workflow automation converge. Abbott positioned the i-STAT TBI Plasma test as a standard-of-care complement to CT, not a replacement. Meanwhile, Abbott is reportedly pursuing further FDA clearances for use on lab hardware platforms like Alinity i and Architect, signaling a strategy to span both bedside and centralized lab environments.

Sources:

Here’s the industry shift: as more rapid tests become available, the bottleneck becomes what you do with the result. If a clinician gets a biomarker result in 15 minutes but the organization can’t:

  • document it cleanly in the EHR,
  • trigger the right clinical pathway,
  • notify the right team,
  • schedule follow-up,
  • and track outcomes,

…then the value is muted.

That’s where AI consulting and workflow automation become essential—not as “AI for AI’s sake,” but as clinical operations engineering.

Practical automation ideas: how to operationalize TBI biomarker testing with n8n workflows

At our AI consulting practice, we often see healthcare and medtech teams adopt new diagnostics faster than they can adapt workflows. Tools like n8n (an automation and integration platform) are a pragmatic way to orchestrate multi-system processes without building everything from scratch.

Below are example n8n workflows that can turn point-of-care results into reliable, auditable action.

1) Result-to-triage workflow (ED/urgent care)

Trigger: i-STAT result posted to LIS/EHR interface (HL7/FHIR feed) or captured via a secure intake form.
Logic:

  • If Not Elevated, suggest guideline-aligned next steps (e.g., avoid CT when clinically appropriate), generate discharge instructions template, and create a follow-up reminder.
  • If Elevated, route to clinical escalation: notify ED physician, suggest CT consideration, create observation checklist, and open a structured note.

n8n nodes you might use:

  • Webhook (result ingestion)
  • IF / Switch (decision logic)
  • HTTP Request (FHIR API calls)
  • Email/SMS (secure messaging via approved channels)
  • Database (audit logs)

2) Automated follow-up for high-risk biomarker profiles

Given the reported link between high biomarker levels and 6-month outcomes (with greatest risk concentrated in the first month), organizations can automate “care continuity” tasks:

Trigger: Elevated biomarker result + discharge order.
Actions:

  • Schedule a neurology or concussion clinic appointment slot
  • Create a patient outreach ticket (call center)
  • Send educational materials
  • Trigger symptom monitoring check-ins (weekly for 4 weeks)
  • Escalate if symptoms worsen

This is where workflow automation reduces leakage—patients who should get follow-up often don’t, especially after a “normal CT.”

3) Analytics and model governance workflow

If you’re using biomarker results for operational decisions, you need monitoring:

  • CT utilization changes
  • Return visits within 72 hours / 7 days
  • Missed intracranial lesions
  • Time-to-decision
  • Outcomes by cohort

n8n can orchestrate:

  • nightly pulls from EHR/LIS
  • de-identification and aggregation
  • dashboards (BI tools)
  • alerting when metrics drift

This is also foundational if you plan to add AI layers later (risk scoring, triage optimization, capacity forecasting). Good automation makes AI safer because it enforces data quality and traceability.

Actionable takeaways for developers, tech leaders, and innovators

For healthcare IT and engineering teams

  1. Design for “time-to-action,” not just time-to-result. A 15-minute test is only valuable if your systems route it to a decision point quickly.
  2. Prioritize interoperability early. Decide whether results will flow via HL7, FHIR, or secure middleware—and document the mapping (GFAP/UCH-L1 flags, units, reference ranges, timestamps).
  3. Implement auditability by default. Any workflow that influences imaging decisions should log inputs, outputs, user overrides, and timestamps.

For product and innovation leaders

  1. Treat point-of-care diagnostics as a platform, not a device. The device creates a data stream; the differentiation comes from pathways, follow-up, and outcomes tracking.
  2. Plan for multi-setting deployment. Abbott’s mention of i-STAT Alinity availability outside the U.S. and the pursuit of broader platform clearances (Alinity i, Architect) implies heterogeneous environments—build workflows that are portable across sites.

For clinicians and operational leaders (with a tech lens)

  1. Use biomarkers to complement CT, not compete with it. The strongest story here is better targeting of imaging and improved identification of otherwise missed cases.
  2. Build structured pathways for “CT-negative but biomarker-elevated” scenarios. That’s where standard workflows often fall short.

The big picture: from diagnostics to decision intelligence

Abbott’s CES 2026 spotlight is a reminder that modern diagnostics is converging with:

  • edge computing (handheld analyzers),
  • ultra-sensitive assays (picogram-level detection),
  • and workflow intelligence (automation + AI-enabled decision support).

It also exposes a critical industry challenge: healthcare doesn’t lack data—it lacks reliable orchestration. As point-of-care testing proliferates, the winners will be organizations that can convert results into consistent actions, at scale, with measurable outcomes.
