- Brief Summary
The primary objective of the clinical trial is to evaluate the effect of time on levels of Ubiquitin C-terminal Hydrolase-L1 (UCH-L1) and Glial Fibrillary Acidic Protein (GFAP) biomarker levels in a population of head injured subjects over the age of 18 presenting acutely with a Glasgow Coma Scale score 13-15 as well as in a group of uninjured control subjects.
