Blood Test May Eliminate Need for CT Scans after TBI (Healio)

The University of Rochester School of Medicine and Dentistry studied the accuracy of a TBI diagnostic blood test created by UF startup and Sid Martin Biotech graduate Banyan Biomarkers.

A novel blood test predicted the absence of intracranial injuries on head CT scan after suspected traumatic brain injury with high accuracy, according to findings published in The Lancet Neurology.

“More than 50 million people worldwide sustain a traumatic brain injury (TBI) annually,” Jeffrey J. Bazarian, MD, from the University of Rochester School of Medicine and Dentistry, and colleagues wrote. “Detection of intracranial injuries relies on head CT, which is overused and resource intensive. Blood-based brain biomarkers hold the potential to predict absence of intracranial injury and thus reduce unnecessary head CT scanning.”
