Can A New Blood Test Diagnose TBI In The Field?

A study published by Dr. Linda Papa of Orlando, Florida, on November 10, 2011 in the Annals of Emergency Medicine found that patients with TBI had a significantly higher amount of an acidic protein in their blood than those without TBI. The protein at issue is called glial fibrillary acidic protein (GFAP). Dr. Papa said the test, which must be done within four hours after the injury, may be used someday in the field to diagnose TBI in wounded soldiers. She also said the test could help determine which patients with head trauma need or don’t need a head CT scan at a hospital.
