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.

What increases my risk for an elevated INR?
According to this modified score, patients with bilirubin and creatinine values below 1 mg/dL (17 and 90 Î¼mol/L, respectively) are rounded off to 1 mg/dL to avoid negative logarithmic values. Similarly, patients with INR below 1 are rounded off to 1. Whatever the individual values, the score is empirically capped at 40.ndependent of the cause of cirrhosis, high MELD score was shown to be associated with a decrease in residual liver function as measured by monoethylglycinexylidine test. The particular issues of alcoholic cirrhosis, HCC, nontransplant surgery, and transplantation are detailed below.
