Biomarker Testing for Head Trauma
(BRAIN-CT Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether a simple blood test (Alinity Whole-blood TBI biomarker i-STAT) can assist doctors in deciding when to use a head CT scan after a mild head injury. The goal is to reduce unnecessary imaging in the emergency room, ensuring scans are performed only when needed. Participants will have their blood tested to determine if this method enhances decision-making for head scans. The trial seeks individuals who experienced a mild head injury (feeling dazed or confused) within the last 24 hours and have not yet undergone a head scan for this injury. As an unphased trial, it offers participants the opportunity to contribute to innovative research that could improve emergency room practices.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this blood test is safe for use in head trauma cases?
Research shows that the Alinity Whole-blood TBI biomarker i-STAT quickly provides lab-quality results for assessing mild traumatic brain injury (mTBI). People usually tolerate this blood test well, experiencing few negative side effects. Tests with blood samples from donors have proven it can provide reliable information without harming the person tested. However, the test does not predict long-term effects after a head injury. It primarily helps determine if immediate care, such as a CT scan, is necessary. Overall, evidence suggests the test is safe for use in people.12345
Why are researchers excited about this trial?
Researchers are excited about the Alinity Whole-blood TBI biomarker i-STAT because it offers a rapid and less invasive way to assess head trauma. Unlike the standard practice of using CT scans, which can expose patients to radiation and require more time, this biomarker test provides immediate results from a simple blood sample. This could allow healthcare providers to make quicker decisions about the need for further imaging, potentially reducing unnecessary scans and improving patient care.
What evidence suggests that this blood test is effective for deciding when to use a head CT scan for mild head injury?
Research has shown that the Alinity Whole-blood TBI biomarker i-STAT test can assist doctors in determining the necessity of a head CT scan after a mild head injury. This test detects specific proteins, GFAP and UCH-L1, released when the brain is injured. It delivers quick, accurate results at the patient's bedside in about 15 minutes. In this trial, participants in the Published Biomarker Group will have their biomarker results provided to the ED provider immediately, potentially reducing unnecessary CT scans, lowering radiation exposure, and speeding up care decisions. Meanwhile, participants in the Blinded Biomarker Group will not have their biomarker results disclosed during the decision-making process for cranial imaging. The FDA has approved this test, indicating trust in its ability to help evaluate brain injuries.12467

What Are the Treatments Tested in This Trial?
Interventions
- Alinity Whole-blood TBI biomarker i-STAT
Trial Overview
The study is testing the effectiveness of a blood test using the Alinity Whole-blood TBI biomarker i-STAT to determine if it can guide doctors on when to perform a CT scan after mild cranial trauma.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Active Control
Biomarker results are provided to the ED provider immediately and before the decision to order a head CT is made. A print-out of the results will be handed to the provider or uploaded to the epic platform.
Biomarker results are not disclosed during the decision-making process for cranial imaging.
