The prothrombin time (PT) is a test that helps evaluate your ability to appropriately form blood clots. The international normalized ratio or INR is a calculation based on results of a PT that is used to monitor individuals who are being treated with the blood-thinning medication (anticoagulant) warfarin (Coumadin). Primary care, urgent care, and hospitals demand fast, reliable PT/INR testing for the monitoring of oral anticoagulation therapy (OAT) with warfarin. Trust Lynn Medical to deliver on a device that tests PR/INR with clinical accuracy.
