The first blood test to help doctors diagnose traumatic brain injuries (TBI) has won FDA approval and can be used to detect it for armed forces, Army researchers announced recently.

The test “sets the stage for a more modernized standard of care for testing of suspected cases,” FDA Commissioner Scott Gottlieb said in a statement.

“This may be a beginning. It’s not the pot of gold at the end of the rainbow,” Dr. Walter Koroshetz, director of the National Institute of Neurological Disorders and Stroke, said.

“There are blood tests for many diseases on the market, but this is the first one dedicated to traumatic brain injury,” said Army Lt. Col. Kara Schmid.

Traumatic brain injuries affect an estimated 10 million people globally each year.

The Army had 220,014 TBI cases, the Navy had 50,937 cases, the Air Force had 50,995 cases, and the Marine Corps had 53,284 cases. The U.S. military had a grand total of 375,230 cases, according to Defense Department records.
