A new rapid blood test that can reportedly detect brain injuries like concussions in just minutes has cleared a major hurdle toward becoming widely available for use in the U.S.

And for decades, the process of detecting head trauma in patients has primarily been based on subjective doctor assessments or required blood samples to be sent off to a lab for processing and testing.
