You may be confused: INR is a measure of blood clotting and is often kept at about 2 if you are on warfarin. An INR of 11 would be EXTREMELY dangerous and put you at very high risk of bleeding On the other hand, prothrombin levels measure a specific clotting factor and may have normal values (not on anticoagulants) near 11 depending on a particular lab.
