Blood Test for TBI on the Horizon

Researchers at the University of Florida’s McKnight Brain Institute recently found that soon we may be able to detect the severity of a brain injury by testing blood samples soon after the injury occurs.

The theory goes something like this: when a TBI occurs, the injured brain cells release a chemical, and by measuring that chemical’s level in the bloodstream, we may be able to get an idea of how extensive the damage may be:

“The NF-H protein can be detected with a widely used screening method called ELISA, or enzyme-linked immunosorbent assay. Shaw developed antibodies that react positively to the presence of NF-H. Now he wants to apply the assay method to other proteins that may be potential biomarkers. He also wants to shorten the time to get results; with ELISA testing the process takes a couple of hours.”

By being able to perform blood tests for TBI, we may be on the brink of a new classification level for different kinds of brain injuries. There isn’t word yet on whether the blood test is effective for anoxic injuries or stroke.
