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].
The international normalized ratio (INR) is a standardized number that's figured out in the lab. If you take blood thinners, also called anti-clotting medicines or anticoagulants, it's especially important to check your INR. The INR is figured out using the results of the prothrombin time (PT) test. This measures the time it takes for your blood to clot. The INR is an international standard for the PT.
