S100B
Serum concentrations >0.48 μg/L in <6 hours predictive of Glasgow Outcome Scale Extended (GOSE) scores of <5 (severe disability) at 1 month post injury Extracerebral injuries have significant impact on predictive ability of S100B
Elevations primarily found in patients with a focal mass lesion (V to Marshall VI) When Marshall is combined with GFAP, it produces superior sensitivity and specificity for TBI
Serum concentrations peak 48–72 hours after injury and can remain elevated for 2 weeks Potential biomarker of intracranial haemorrhage and axonal injury
