International Normalized Ratio (INR) is a blood test that measures the time it takes for blood to clot. Learn more about what INR test results mean for you. International Normalized Ratio (INR) is a blood test that measures the time it takes for blood to clot. This test is usually administered to people taking anticoagulants or blood thinners. INR Levels. The lower the INR number, the shorter it takes for blood to clot and the greater risk you have for blood clots.
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). normal INR is approximately 1.0. People taking the blood thinner warfarin typically have a target INR of 2.0 to 3.0. People with an INR higher than the normal range who arenât taking warfarin may have a medical condition that needs further evaluation. A low INR is rarely significant.
