Take Home Message: The Tau-A biomarker is a potential biomarker to distinguish those at risk for prolonged recovery following a concussion.
Diagnosis and return to play following a concussion rely heavily on subjective information from athletes. Thus, there is a great need to develop an objective tool, such as a blood test, to diagnose and monitor a concussion. Therefore, the authors evaluated professional Swedish ice hockey players to determine the utility of 2 fragments of tau (tau-A & tau-C) for diagnosis and prognosis of sports-related concussions.
