A prothrombin time (PT/INR) test measures how fast a blood sample forms a clot. Healthcare providers often do this test to monitor how fast your blood clots if you’re taking the blood thinner warfarin. It’s also used to diagnose blood disorders.
A high PT/INR means your body takes longer than normal to form blood clots. An international normalized ratio (INR) is a blood test that indicates how well the blood is able to clot. People who take warfarin (Coumadin) need to monitor this level to make sure it doesn’t go too high or too low. A normal INR range is 0.8 to 1.1 if you’re not taking anticoagulant medications.

The International Normalized Ratio (INR) measures how quickly blood clots. This standardized test is important for individuals on blood-thinning medications, helping healthcare providers manage treatment and maintain clotting balance.
