The INR test measures how quickly your blood clots while on Warfarin. A high INR indicates slower clotting time. However, factors like a vitamin K-rich diet, certain medications, or medical conditions can affect how Warfarin works, leading to clots despite high INR levels.

A normal, healthy person will have an INR of 1. In warfarin therapy, an INR is usually aimed for around 2.INR is the international normalized value for prothrombin time. It is a value that measures the extrinsic pathway of clotting, and is often used to determine how quickly the person will make clots. It is often used to determine if the patient is on therapeutic doses of blood thinners.
