The Food and Drug Administration on Wednesday approved the Banyan Brain Trauma Indicator, the first-ever blood test to detect signs of a traumatic brain injury.
The test identifies two proteins that appear in the blood within 12 hours of a serious brain injury, the Los Angeles Times reports. The levels of those proteins can then predict which patients may have brain lesions that can be seen on a CT scan and which won't. Test results come back about four hours later, but Banyan Biomarkers Chairman and CEO Henry Nordhoff told the Times they are working on creating a test with a turn-around of less than an hour.
