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].
INR stands for international normalized ratio. The INR provides some information about a personâs bloodâs tendency to clot (which is often described as how âthinâ or âthickâ their blood is). The INR comes from the conversion of another value, the prothrombin time (PT). Prothrombin time is the time it takes for blood to clot in a test tube. A high or low PT can suggest bleeding or clotting tendencies. Most often, the PT is checked to monitor a personâs response to blood thinners such as warfarin (Coumadin).
