The Food and Drug Administration has approved the first blood test to evaluate concussions, otherwise known as mild traumatic brain injuries, in patients after accidents, military wounds, sports collisions and other causes. The blood test from Banyan Biomarkers Inc. could be useful in diagnosing brain injuries that lead to an estimated 2.5 million emergency-room visits each year. The World Health Organization estimates about 10 million people world-wide are affected by mild traumatic brain injuries.
