The Coag-Sense system is used to test prothrombin time (PT) in patients taking Warfarin for oral anticoagulant therapy. Results are reported as International Normalized Ratio, or INR units, and PT seconds.
Because the system directly detects clot formation, it reports true PT-seconds. The Coag-Sense system consists of a meter and single-use PT strips and control strips, along with certain accessories required for testing.
