I'm not really what you're specifically asking but here's what I can say: Prothrombin time, also known as INR is used to monitor blood clotting in people who take warfarin (a medicine to prevent blood clotting). The dose of warfarin should be enough to delay clotting a little, but not too much which may cause bleeding problems. The reference range for prothrombin time is usually around 12–15 seconds; the normal range for the INR is 0.8–1.2. INR for people on warfarin therapy is 2.0–3.
