Blood Biomarker Testing

After a brain injury, it’s not always easy to see what’s going on beneath the surface, especially when scans like CTs or MRIs come back “normal,” but something still feels off. That’s where blood biomarker testing is starting to change the game. These tests look for specific proteins or molecules that are released into the bloodstream when the brain is injured, giving doctors another way to understand what’s happening. Markers like GFAP, UCH-L1, S100B, and tau can sometimes detect injury even when imaging doesn’t, and they’re now being used in some ER settings to help decide whether a CT scan is really needed. Other tests are still in the research phase but show promise for tracking healing, guiding care, and even predicting long-term outcomes. As the science grows, blood biomarker testing may offer a more personalized path forward in brain injury recovery. Click any of the options below to learn more.
