Evaluation of a blood test for traumatic brain injury

Evaluation of the Abbott i-STAT TBI Biomarker Test for Effect on Decreasing CT Utilization Among Adult Emergency Department Patients With Suspected Traumatic Brain Injury

NA · Icahn School of Medicine at Mount Sinai · NCT06766435

This study is testing a new blood test to see if it can help doctors quickly diagnose mild traumatic brain injuries in adults who have recently had a head injury.

What this trial studies

This clinical trial evaluates the Abbott i-STAT TBI biomarker test, which measures specific proteins in the blood to aid in the diagnosis of traumatic brain injury (TBI). The test aims to provide a quicker and more efficient alternative to traditional head CT scans, particularly for patients with mild TBI. By using the i-STAT Alinity instrument, the study seeks to improve clinical decision-making in emergency care settings. Participants will be adults who have sustained a head injury within the last 24 hours and are awaiting a CT scan as part of their routine care.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have experienced a head injury within the last 24 hours and have a Glasgow Coma Scale score between 13 and 15.

Not a fit: Patients who have signs of severe head injury, such as suspected stroke or skull fractures, may not benefit from this study.

Why it matters

Potential benefit: If successful, this test could reduce unnecessary CT scans, decrease emergency department wait times, and minimize radiation exposure for patients with mild TBI.

How similar studies have performed: Other studies have shown promise in using biomarker tests for TBI diagnosis, indicating that this approach may be effective.
