METHODS FOR AIDING IN THE HYPERACUTE DIAGNOSIS AND DETERMINATION OF TRAUMATIC BRAIN INJURY IN A HUMAN SUBJECT USING EARLY BIOMARKERS

Abstract:

Disclosed herein are methods that aid in the hyperacute diagnosis and evaluation of a human subject that has sustained or may have sustained an injury to the head, such as mild or moderate, severe, or moderate to severe traumatic brain injury (TBI), using an early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) glial fibrillary acidic protein (GFAP), or a combination thereof. Also disclosed here are methods that aid in the hyperacute determination of whether a human subject that has sustained an injury or may have sustained to the head would benefit from and thus receive a head computerized tomography (CT) scan based on the levels of UCH-L1. These methods involve detecting levels of early biomarker, such as ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) glial fibrillary acidic protein (GFAP), or a combination thereof, in samples taken from a human subject at a time point within about 2 hours, such as about 10, 12, or 20 minutes, after the subject has sustained or may have sustained an injury to the head.
