What is INR?

No, this is not the Indian Rupees. But a medical term.

INR stands for Internationational Normalized Ratio. It is used to determine the clotting tendency of blood. A high INR level indicates a higher chance of bleeding and a low INR level indicates a high chance of having a clot.

It is one of the mandatory blood tests which is performed before an Angio.
