To determine whether combining acute serum biomarkers UCH-L1 and GFAP improves diagnostic accuracy and outcome prediction in traumatic brain injury compared to single-biomarker evaluation.
Interventional investigation (ClinicalTrials.gov Identifier NCT01565551) evaluating N=206 patients with traumatic brain injury across a multicenter cohort.
Serum levels of UCH-L1 and GFAP were measured acutely and compared against healthy controls, acute intracranial lesions on CT scans, and 3-month functional recovery via the Glasgow Outcome Scale Extended (GOS-E).
UCH-L1 and GFAP levels correlated weakly (r=0.364), while combining both biomarkers achieved superior discrimination of TBI from healthy controls (AUC 0.94) compared to GFAP alone (AUC 0.91) or UCH-L1 alone (AUC 0.87).
Both biomarkers detected CT-identified intracranial lesions, with GFAP demonstrating significantly higher sensitivity and specificity than UCH-L1 (AUC 0.88 vs. 0.71).
Neither biomarker demonstrated adequate sensitivity and specificity for predicting 3-month outcomes (GFAP AUC 0.65–0.74; UCH-L1 AUC 0.59–0.80 across GOS-E cutoff thresholds).
