Concussion Can Now Be Diagnosed With This Cheap And Simple Method

Most knocks on the head don't result in concussions--fortunately.
So why subject patients--and the healthcare system--to costly CT scans?
The FDA has approved a new blood test that will identify concussions.
The test can predict which blood samples indicate concussions 97.5% of the time.
So healthcare professionals can rule out the need for a scan in at least one-third of patients.
