Blood Test for Concussion OK'd

Blood Test for Concussion OK'd

Medical industry news site Medscape reports that the US Food and Drug Administration has approved a blood test called the Brain Trauma Indicator that can be deployed in the first instance, saving the CT scans for confirmed cases.

Sporting injuries dominate conversations about the need to prevent and detect concussion.

Test results can be available within 3-4 hours.

The new test - dubbed the Brain Trauma Indicator - is created to help determine the need for such scans after head injuries, reducing unnecessary CT testing and associated radiation exposure, the agency said. The test will first be used in emergency rooms, possibly as soon as later this year, but Banyan's hope is that it will eventually be used on battlefields and football fields.

For more information, see the entire story below. "A blood-testing option for the evaluation of mTBI/concussion not only provides health care professionals with a new tool, but also sets the stage for a more modernized standard of care for testing of suspected cases".

Known as the Banyan Brain Trauma Indicator, it could help reduce the need for CT scans and thus decrease radiation exposure to patients, according to the FDA.

Traumatic brain injuries affect an estimated 10 million people globally each year; at least 2 million of them are treated in US emergency rooms. It predicted no evidence of damage on a CT scan 99.6 percent of the time.

The FDA assessed information from a multi-focus, planned clinical investigation of 1,947 individual blood tests from grown-ups with suspected mTBI/blackout and surveyed the item's execution by contrasting mTBI/blackout blood tests comes about with CT filter comes about.

"It's a time saver, a cost saver and there's no radiation exposure", Zafonte said.

The test can help doctors identify which patients would require computed tomography (CT) scan to check if they have brain damage. Being able to predict whether patients have a low probability of intracranial lesions can help healthcare professionals manage patients and decide whether or not to perform a CT scan. But mild traumatic brain injuries affect a far wider demographic than that suggests. He was not involved in the development of the test.

Symptoms can occur at different times and also vary from person to person, these are the challenges of diagnosis concussions.

Other companies are developing similar blood tests to detect brain injuries. Those are incredibly good odds, and considering the test costs as little as one-tenth as much as a CT scan, it's a huge win for modern medicine.
