About

The goal of this study is to evaluate the i-STAT TBI test to assist determining the need for a computed tomography (CT) scan in patients with suspected mild traumatic brain injury (TBI).

Patients will be asked to provide a blood sample.

Full description

The purpose of this study is to evaluate the clinical performance of the i-STAT TBI test for the proposed intended use; to assist in determining the need for a computed tomography (CT) scan in patients presenting with suspected mild traumatic brain injury (TBI) who are 18 years of age or older.

The secondary objective of this study is the collection of additional data and specimens from all study subjects that may support other purposes related to the understanding of TBI.

Enrollment: 1,106 patients

Sex: All

Ages: 18+ years old
