You need to calculate the International Normalized Ratio (INR) of patients prior to the administration of Warfarin (Coumadin).

Warfarin is a prescription medication that interferes with normal blood clotting (coagulation). In some countries, Warfarin is sold under the brand name Coumadin. Warfarin is prescribed to those people who are at increased risk of developing harmful blood clots. Before the prescription of Warfarin, the blood test, known as prothrombin time, is used to calculate International Normalized Ratio (INR). INR helps the healthcare provider to determine how well Warfarin is working to prevent blood clots and whether the dose needs to be adjusted.
