Blood test detects even mild concussion

Two blood biomarkers can detect even mild forms of concussion, in both adults and children, a study shows.
The biomarkers are glial fibrillary acidic protein (GFAP), expressed almost exclusively in astrocytes, and ubiquitin C-terminal hydrolase (UCH-L1), found in neurons.
Last year, the US Food and Drug Administration approved use of GFAP and UCH-L1 in adults with mild to moderate traumatic brain injury to help determine the need for a CT scan.
However, the ability of these two biomarkers to detect concussion in adults or children had not been determined.
