INR is a ratio that accounts for the different chemicals present in blood to standardize the results of a prothrombin time test, according to Mayo Clinic. Prothrombin time is the amount of time in seconds that it takes for blood clotting to occur. The rate of clotting slows as INR rises, according to Drugs.com.

INR results in the range of 2 to 3 are good for people taking blood thinners, according to the Mayo Clinic. Symptoms that may indicate high INR include cuts that bleed continuously, bruising easily, and bleeding from the gums or nose, according to Drugs.com.

When INR is too high, treatment recommendations include skipping an anti-coagulant dose or administering vitamin K, according to University of California San Diego School of Medicine. Treatment may include transfusion of clotting factors, platelets and plasma, according to Drugs.com. Factors that put patients at risk for high INR include liver problems, congenital clotting problems, low levels of proteins necessary for clotting and dosing problems with blood thinning medications, states Mayo Clinic.
