NEW YORK (360Dx) – Even as the deaths of former National Football League players have put the spotlight on concussions, diagnosing the injury remains a tricky business, sometimes relying on art as well as science.

Boston-based BioDirection hopes to change that with a blood-based test that it said can offer an objective diagnosis within 90 seconds. If all goes according to plan, the test could hit the market in Europe in about a year, followed by a launch in the US.
