Discovery of the day
A novel whole-blood point-of-care test measuring glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase L1 (UCH-L1) has received U.S. FDA clearance for predicting intracranial injury on head CT within 24 hours of traumatic brain injury (TBI). Researchers demonstrated that the test achieved high sensitivity and negative predictive value, enabling rapid triage and clinical decision-making in suspected TBI cases. For a nurse and psychologist working in chronic disease prevention and health behavior, this advancement underscores the growing role of accessible biomarker-based diagnostics in reducing unnecessary imaging and improving early identification of neurological injury, particularly relevant to fall-related head trauma prevention in older adults.
