causes of elevated baseline inr
What is an elevated INR? The INR, or International Normalized Ratio, is a measure of how long it takes your blood to clot. A prothrombin time (PT) is a another blood test done to help measure your INR. The higher your PT or INR, the longer your blood takes to clot. An elevated PT or INR means your blood is taking longer to clot than your healthcare provider believes is healthy for you. When your PT or INR is too high, you have an increased risk of bleeding.
