My INR is 1.4 . what does it mean? INR stands for International Normalized Ratio. 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.

What is an INR blood test? Does 3.7 inr mean blood is too thick? An INR of 3.7 means that the blood is thinner than usual, a normal person without taking any blood thinning medication such as warfarin theres would be less than 1.0 - meaning… the blood is normal consistancy.

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.

What is INR? To solve this problem, the international normalized ratio (INR) was created. By entering a PT result into a math formula, it yields the INR. The international normalized ratio means one lab’s test results can be compared to another’s with high accuracy. A normal INR is approximately 1.0.

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.

- If the inr is too high, there is a risk of uncontrolled bleeding. The inr helps in monitoring the dose of blood thinners. In people not on blood thinners, the inr is about 1.0. For patients on blood thinners, the inr should generally be between 2.0 and 3.0 for treating blood clots in the lungs.

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.nternational 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.

Overview 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.

Prothrombin Time and International Normalized Ratio (PT/INR) The international normalized ratio or INR is a calculation based on results of a PT that is used to monitor individuals who are being treated with the blood-thinning medication (anticoagulant) warfarin (Coumadin®).

Normal INR Levels Normal INR Levels are 2.0 to 3.0 for people with the following conditions1. As an example, we are going to use an INR of 2.5 because usually an INR of 2.5 is a normal INR level for someone taking Warfarin. What an INR Level of 2.5 means. An INR Level of 2.5 is optimal and is inside your therapeutic INR range of 2-3.

- INR Test. Share this page: Tweet. The INR is a test of blood clotting, which is primarily used to monitor warfarin therapy, where the aim is to maintain an elevated INR in a certain range eg, 2.0 to 3.0. It is initially checked frequently, but as treatment is stabilised it may be done less often, eg fortnightly.

Normal INR Levels The normal range for a healthy person not using warfarin is 0.8–1.2. However, this is a dangerously low INR for a person using Warfarin.

- A: INR, or international normalized ratio, is a blood test done to check how thick or thin the blood is. INR is used to monitor Coumadin (warfarin) therapy. Coumadin is a blood thinner used to prevent blood clots in patients with a history of clots or certain heart conditions.oumadin (warfarin) is a blood thinner used to prevent the formation of blood clots, to prevent heart attacks and strokes. When you're on warfarin, your doctor must monitor your INR levels to ensure that your blood is not too thin, which can lead to an increased risk of internal bleeding.

- The international normalized ratio (INR) is a calculation based on results of a PT and is used to monitor individuals who are being treated with the blood-thinning medication (anticoagulant) warfarin (Coumadin®). PT and INR are ordered on a regular basis when a person is taking the anticoagulant drug warfarin to ensure that the prescription is working properly and that the PT/INR is appropriately prolonged. There is no set frequency for doing the test.

INR Tests The higher the INR number, the longer it takes for blood to clot and the greater risk you have of bleeding. Most healthy people will have an INR of 0.9 - 1.3. 1 Patients who are taking blood thinners such as Warfarin are usually considered therapeutic by their doctors when their INR is between 2.0 and 3.0.

Overview 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. What your results mean Clotting too slowly. Blood that clots too slowly can be caused by: Blood-thinning medications ; Liver problems

What is INR? 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 person’s 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 aren’t taking warfarin may have a medical condition that needs further evaluation. A low INR is rarely significant.

Use of INR for monitoring warfarin treatment In most situations the INR target is 2.5 (target range 2.0 – 3.0). This range is appropriate for the prophylaxis or treatment of venous thromboembolism and reduction of the risk of systemic embolism for people with atrial fibrillation and valvular heart disease.5 In some situations higher ranges are more appropriate.

PT INR Normal Values If the PT INR values are found on the higher end of the normal range, bleeding and other related events will likely occur. On the other hand, if the PT INR values are found on the lower end of the spectrum, inappropriate blood clotting may occur.

INR Levels INR Levels. For people taking blood-thinning medications, it is important to make sure that the medication is working properly to avoid serious complications. To help ensure safe treatment, a healthcare provider will take a blood sample and test how long it takes the blood to clot.f your INR falls below the normal levels, your blood may clot too quickly and increase your risk for a stroke. (Click INR for more details on the specific levels of INR that are considered within a normal range, as well as information on how often this ratio needs to be checked.). Advertisement.

INR Tests 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. The lower the INR number, the shorter it takes for blood to clot and the greater risk you have for blood clots.

PT INR Normal Values PT INR normal values are important figures that help doctors determine the ability of a person’s blood to clot. The standard values of PT INR may vary from lab to lab, and so it is very important to have the PT INR results interpreted by qualified physician. Doctors can determine the occurrence of improper and dangerous blood clotting by comparing the PT INR test results to the normal values set by the laboratory.
