Blood test to help decide if you need a CT scan after a head injury
Part of Brain & nervous system, Injuries & trauma clinical trials.
This study tests a blood test that may help doctors decide if you need a CT scan after a mild head injury. If the test works, you might avoid a CT scan and get faster answers about your head injury.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older and arrive at the emergency department within 24 hours of a head injury.
- The injury must involve your head being struck, hitting a hard surface, or a sudden strong motion that could shake your brain.
- You must have a mild level of consciousness after injury (GCS 13-15).
- You cannot be taking blood-thinning medications (like warfarin, apixaban, or clopidogrel).
- Doctors must not have already decided to do a CT scan of your head, because the study aims to see if a blood test can avoid that scan.

This study looks at whether getting a CT scan is required when someone has a head injury and is already taking medicine that prevents platelets from clotting. It may help doctors safely decide who truly needs immediate imaging after certain head injuries.
This study looks at how people with mild head injuries are treated and recover. It may help doctors improve care for patients who have a mild head injury and get a brain scan.
This study is testing a new blood-based test to help doctors diagnose traumatic brain injury (TBI) and track recovery or complications. If you have had a head injury and a CT scan as part of your care, you may be able to join.
This study looks at whether routine blood tests taken in the emergency room can help doctors predict if a child with a minor head injury might have a brain injury. The goal is to find simple, quick ways to identify children who may need extra care.
This study tests whether a combination of blood tests and eye-tracking can help doctors decide if a head CT scan is needed and predict recovery after a mild head injury (concussion). It aims to make care more accurate and less stressful.
This study uses a blood test to help doctors better understand and manage mild traumatic brain injury (concussion). If you had a mild head injury in the past 12 hours and have certain symptoms, researchers want to check if a new blood-based approach can improve care.
