29, 2019 (HealthDay News) -- Plasma concentration of glial fibrillary acidic protein (GFAP) can aid in detecting traumatic brain injury (TBI) by identifying patients with negative findings on computed tomography (CT) scan who might need magnetic resonance imaging (MRI) and additional follow-up, according to a study published online Aug.
