New research bolsters evidence that a simple blood test may someday be used to detect concussions.
It suggests that a protein linked with head trauma may be present in blood up to a week after injury, which could help diagnose patients who delay seeking treatment.
The study involved patients at one hospital in Florida and the results are preliminary — a concussion blood test based on the two proteins studied or on other so-called biomarkers under review is likely at least a few years away from routine use.
But the new findings “are a substantial step” in developing a test that could be used in broad settings, from the battlefield to sports events and doctors’ offices. That’s according to an editorial published with the study Monday in JAMA Neurology.
