Spit Test

Spit test could be way of the future for concussion testing

A three-year research project involving more than a thousand professional men's rugby players found the biomarkers can show if a player is concussed, and also how a player's body is responding to the trauma several hours to several days later.

"Crucially, the differences in the salivary concentration of these biomarkers are measurable within minutes of injury, which means we can make rapid diagnoses," said Antonio Belli, a professor of trauma neurosurgery at Birmingham University who co-led the study.
