For blood-biomarkers, there were no differences between arrival time categories for NfL, UCH-L1, and GFAP.Conclusions: Mechanism of injury, age, and race are identifiable factors that may influence both arrival time at ED and clinical outcomes and interpretation of biomarker results after TBI. Since our cohort mostly presented within 12 hours, and CT and biomarker results were not influenced, future research should focus on a small cohort of patients with ED presentation beyond 12 hours.Disclosure: Mr. Anandarajah has nothing to disclose.
