As per the study published in the Lancet Neurology, a simple drop of blood may diagnose accurately a brain injury after trauma over head as a CT Scan does. So, it may be very important for diagnosis in rural area where CT scan is not available or contraindicated for radiation or making CT scan optional one. Investigators studied close to 2000 adult patients who presented to the emergency department (ED) with suspected TBI and who had undergone both head CT and blood collection within 12 hours of the injury.They measured ubiquitin C-terminal hydrolase-L1 (UCH-L1) and glial fibrillary acidic protein (GFAP), 2 biomarker proteins that are released into the bloodstream after TBI or Traumatic Brain Injury.
They found that in more than 96% of patients, a blood test combining both of these biomarkers accurately predicted the absence of acute intracranial injury, as confirmed by CT scan. "We see…
