The i-STAT TBI cartridge is the first point-of-care test that measures the level of biomarkers associated with brain injury in whole blood to help assess patients with mild traumatic brain injury (mTBI) within 24 hours after injury. The i-STAT TBI cartridge provides objective data to help assess patients with suspected mTBI and provides lab-quality results in approximately 15 minutes. It is only available for use on the i-STAT Alinity instrument.
