How Do I Get Tested when Concussion is suspected?
Getting a blood test to help assess a concussion is simple. Blood is drawn from your arm, the sample is processed in the lab and then the test is run using the Alinity i or i-STAT Alinity, with results in 15 or 18 minutes, respectively. The absence of brain injury biomarkers gives doctors more information about whether your brain may be injured. This can help them determine the best next steps for care and a treatment plan.
How Do Concussion Assessment Tests Work?
For decades, standard concussion assessment has stayed the same, with doctors leveraging the Glasgow Coma Scale, a subjective doctor assessment (think: “how many fingers am I holding up?,” “follow the light,” “make a fist”), and CT scans to detect brain bleeds or other visible damage.
We worked with scientists, researchers and doctors for more than a decade to find an objective assessment to complement methods like the above. We focused on measuring the best clues our bodies provide when the brain is injured. Our blood test technology does just that, and now doctors have a new tool to help evaluate the need for a head CT scan in a person who may have suffered a concussion.
Our tests measure two biomarkers in the blood that are released when the brain is injured:Ubiquitin C-terminal Hydrolase L1 (UCH-L1) and Glial Fibrillary Acidic Protein (GFAP). In elevated concentrations, both are commonly associated with brain injury.
Should I Get a Possible Concussion Checked Out?
It’s best to have your injury checked out by a doctor. And doctors can use the concussion blood tests as a way to help assess your condition and determine the best next steps.
Because of how serious concussions can be if left untreated, you should get tested any time you think you or a loved one may have suffered one.
Keep an eye out for symptoms, some of which can take hours or days to show.
Why Is It Important to Know If I Have a Concussion?
Millions of people in the U.S. suffer a concussion each year, but more than half of people who suspect they have a concussion never get it checked. Ignoring the signs of a concussion can lead to serious health risks and complications. Plus, repeated concussions can have long-term consequences on your health, so it’s important to know if you or a loved one has suffered a concussion.
When in doubt, get it checked out.
*Abbott’s i-STAT TBI Plasma and Alinity i TBI tests aid doctors in evaluating a suspected mild traumatic brain injury (such as a concussion) in people 18 and older within 12 hours of injury and specifically help rule out the need for a head CT scan.
