Biomarker Role in Assessing Imaging Needs for Mild Cranial Trauma

"The i-STAT TBI cartridge is a point-of-care, whole-blood, biomarker-based assay that measures the level of biomarkers associated with brain injury in the bloodstream 24 hours after injury. Blood samples (5-10cc of whole blood) will be collected upon admission during a routine blood draw in the ED. These samples will be tested using the iSTAT system for mild TBI biomarkers.~In a subset of admitted patients, serial blood draws and iSTAT testing will be performed at 4, 8, 16, and 24 hours, depending on the patient's length of stay."
