INR

INR, or International Normalized Ratio, is a blood test that measures how quickly your blood clots. It helps doctors monitor patients on blood-thinning medications like warfarin, ensuring the blood remains at a safe consistency—not too thin or too thick. The INR standardizes results, so regardless of where or how the test is done, the numbers are comparable. A typical INR range for many patients on anticoagulants is between 2.0 and 3.0, but the target can vary based on the condition being treated. Regular testing helps manage medication doses and reduce the risk of blood clots or bleeding.
