Rapid, accurate, low-cost blood test to help diagnose concussion

Official title: RACE Study: Rapid, Accurate and Cost-effective Analysis of Glial Fibrillary Acid Protein Using a Hand-held Biosensor for Patient With Concussion in Acute Care and at Home Monitoring

Run by University of Calgary · NCT05588115 · Data updated 2026-11-12

This study will test if a portable biosensor can accurately measure a blood biomarker (GFAP) to help diagnose concussion in adults who come to the emergency department.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–65 with a recent (within 7 days) uncomplicated concussion presenting to the emergency department, or adults 18–65 with a musculoskeletal injury for the comparison group.

Probably not a fit

People with complicated mild TBI (positive neuroimaging), a history of moderate/severe TBI, preexisting neurological or major metabolic disease, or those more than 7 days from injury are not likely to benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will enroll adults (18–65) with uncomplicated concussion and a comparison group with musculoskeletal injury, collecting blood at the initial visit and at 2, 6, and 12 weeks plus brief questionnaires and daily symptom check-ins. Researchers will compare biomarker levels measured by the biosensor to the current laboratory gold-standard assay to determine agreement and accuracy. They will also analyze whether biosensor measurements relate to patients' physical and psychological symptoms over time. The concussion group will be compared to the musculoskeletal group to test whether biosensor signals are specific to brain injury.

Why it matters

Potential benefit: If successful, the biosensor could enable faster, cheaper bedside blood testing to support concussion diagnosis and track recovery.

How similar studies have gone: Prior research supports GFAP as a useful blood biomarker for brain injury, but using a portable biosensor for rapid, low-cost measurement is an emerging approach that is only partially validated.
