Biomarkers of Traumatic Brain Injury With Tbit System

A Prospective, Multi-Center, Non-Randomized Study to Identify Intracranial Hemorrhage by Using an In-Vitro Device, Tbit™ System

A prospective, multi-center, non-randomized, pivotal study to assess the safety and efficacy of the Tbit™ System to aid in patient evaluation, suspected of traumatic brain injury, as adjunct companion test to radiologic standard of care, Cranial Computerized Tomography (CCT).

• Willing and able to provide informed consent or obtain consent from legal authorized representative (LAR)

Exclusion Criteria:

• Suspect of ischemic or hemorrhagic stroke with subsequent incidental trauma based on ED examination
• Subject suspect of need of craniotomy for the acute trauma for this event
• External signs compatible with a depressed skull fracture based on ED exam
• Subject requiring administration of blood transfusion after injury and prior to study blood draw
• Subject for whom timing of injury is unable to be estimated within 1 hour of certainty
• Subject with a condition precluding entry into the CT scanner
• Subject who had neurodegenerative disease or other neurological disorder including dementia, Parkinson's disease, multiple sclerosis, seizures, brain tumors, stroke or TIA within the last 30 days, or history of neurosurgery
