INR = [PTpatient Ã· MNPT]ISI. The INR has no units (it is a ratio) and is determined to one decimal place. The first step of the INR calculation is to ânormalizeâ the PT by comparing it to the mean normal prothrombin time (MNPT), the geometric mean of the prothrombin times of the healthy adult population. In the second step, this ratio is raised to a power designated the ISI, or international sensitivity index.
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 drugs or anticoagulants, it's especially important to check your INR.The INR is figured out using the results of the prothrombin time (PT) test, which measures the time it takes for your blood to clot. The INR is an international standard for the PT.hese include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider. The INR is a ratio, so it's just a number, not a number tied to time or another value.
