TRAC will enable first responders to diagnose patients with trauma-induced coagulopathy rapidly. Currently, coagulopathy tests can only be administered using large, stationary machines over the course of half an hour. Our device will give similar or identical results within a few minutes while remaining portable. TRAC achieves this by performing a temperature-controlled analysis on a sample of blood over 2 minutes. TRAC is designed to be a hand-held, pocket-sized device.
