International normalized ratio 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.NR is based on the ratio of the patient's prothrombin time and the normal mean prothrombin time.

- The test used to monitor the effects of warfarin is called the International Normalised Ratio, or INR. It is a blood test that checks how long it takes for blood to clot. The higher the INR, the longer it will take blood to clot (and the higher the risk of bleeding).

Overview In certain situations, such as having a mechanical heart valve, you might need a slightly higher INR. When the INR is higher than the recommended range, it means that your blood clots more slowly than desired, and a lower INR means your blood clots more quickly than desired.

As its name suggests, one INR result can be compared to another INR result regardless of how or where the result was obtained. So, the INR is really just the standard unit used to report the result of a PT test.There are a few things worth mentioning about the INR. First, an individual whose blood clots normally and who is not on anticoagulation should have an INR of approximately 1.o, the INR is really just the standard unit used to report the result of a PT test.

Summit Medical Group Web Site A small amount of blood is taken from a vein in your arm with a needle. The blood is collected in tubes and sent to a lab. Ask your healthcare provider when and how you will get the results of the test. What does the test result mean? 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. If you are not taking a blood thinner and your values are higher than normal, you may: Have liver disease

What is an INR blood test? This is a test derived from another, the prothrombin ratio. It measures the extrinsic clotting pathway system, commonly used to measure warfarin (blood thinning) drugs. A normal, healthy person will have an INR of 1. In warfarin therapy, an INR is usually aimed for around 2.NR is the international normalized value for prothrombin time. It is a value that measures the extrinsic pathway of clotting, and is often used to determine how quickly the person will make clots.

What are normal inr level ? i take coumadin and levels are 1.1 what happens when gets this low? What does the test result mean? For people taking warfarin, most laboratories report PT results that have been adjusted to the INR. These people should have an INR of 2.0 to 3.0 for basic blood-thinning needs. For some who have a high risk of a blood clot, the INR needs to be higher - about 2.5 to 3.5. The test result for a PT depends on the method used, with results measured in seconds and compared to the normal range established and maintained by the laboratory that performs the test. This normal range represents an average value of healthy people who live in that area and will vary somewhat from lab to lab.

- Prothrombin Time and INR. Guide. Prothrombin time (PT) is a blood test that measures how long it takes blood to clot. A prothrombin time test can be used to check for bleeding problems.

International Normalized Ratio INR, standardized prothrombin time. This blood test looks to see how well your blood clots. 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.

What Do Your PT, PTT & INR Results Mean? International Normalized Ratio Blood Test-INR Normal INR Values: 1 to 2 The INR is used to make sure the results from a PT test is the same at one lab as it is at another lab. In the 1980s the World Health Organization determined that patients may be at risk because the results of a PT test would vary from one lab to another, based upon the way the test was done.

Overview A number lower than that range means blood clots more quickly than normal. As INR. This ratio — which allows for easier comparisons of test results from different laboratories — is used if you take blood-thinning medications. In healthy people an INR of 1.1 or below is considered normal. An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking warfarin for disorders such as atrial fibrillation or a blood clot in the leg or lung. In certain situations, such as having a mechanical heart valve, you might need a slightly higher INR. When the INR is higher than the recommended range, it means that your blood clots more slowly than desired, and a lower INR means your blood clots more quickly than desired.
