International normalized ratio (INR) is a calculation made to standardize prothrombin time. INR is based on the ratio of the patient's prothrombin time and the normal mean prothrombin time. Prothrombin time is a test to learn how fast the blood clots in patients receiving oral anticoagulant medication. This test may be used in patients with prosthetic heart valves, venous thromboembolism, or antiphospholipid syndrome[1][2][3][4][5][6][7][8][9]. A blood sample is collected for this test[6][9].
Ask your healthcare provider when and how you will get the results of the test. A PT/INR value higher than normal means your blood is taking longer than normal to form a clot. If you are taking a blood thinner, it means that the medicine is working.NR stands for international normalized ratio. The PT/INR test is usually done when you are taking a blood thinner (anticoagulant) medicine, such as warfarin (Coumadin), to prevent blood clots. Clots can block blood vessels and possibly cause a heart attack or stroke. This test measures the effect of the anticoagulant.
