According to Health.mil, the official website of the U.S. Military health system, the U.S. Food and Drug Administration (FDA) has green-lit a revolutionary new blood-test that can detect the presence of traumatic brain injuries.
Florida-based Banyan Biomarkers, with funding from the U.S. Department of Defense and U.S. Army, created the blood-test, which they have trademarked as the Brain Trauma Indicator (BTI). The test was designed to detect two specific protein markers; Ubiquitin Carboxy-terminal Hydrolase-L1 (UCH-L1) and Glial Fibrilliary Acidic Protein (GFAP).
Research has shown that both UCH-L1 and GFAP appear in the blood at elevated levels up to twelve-hours after a head injury that is significant enough to cause bleeding in the brain.
