what does an inr mean
The international normalized ratio (INR) is a standardized number that's figured out in the lab. If you take blood thinners, also called anti-clotting medicines or anticoagulants, it's especially important to check your INR. The INR is figured out using the results of the prothrombin time (PT) test. This measures the time it takes for your blood to clot. The INR is an international standard for the PT.
