A Study of Biomarkers of Mild Traumatic BRAIN Injury

Patients with mild traumatic brain injury (mTBI) represent a burden of patients admitted to the emergency department. According to the guidelines, a cerebral CT scan is indicated after mTBI according to the specific conditions. However, variability exists regarding the respect of these CT scan indications, and less than 10% of patients will have visible brain lesions on CT scan. Recently, serum Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin C-terminal Hydrolase-L1 (UCH-L1) biomarkers have shown ability to differentiate normal and abnormal CT scan findings after mTBI. These encouraging results prompted us to launch a prospective study using automated and quick measurements of GFAP and UCH-L1 biomarkers to validate these findings.
