Prothrombin Time by Vaughn Aubuchon - Here is a brief simplified chart of human blood INR Range, showing INR levels, and the factors that affect them. This chart illustrates typical therapeutic INR levels, while using Coumadin (warfarin) therapy.
The prothrombin time (PT) is a test used to help diagnose bleeding or clotting disorders. The international normalized ratio (INR) is a calculation based on results of a PT that is used to monitor treatment with the blood-thinning medication warfarin (Coumadin®).
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.
Before you have surgery your doctor may order blood tests to determine how quickly your blood clots. This group of tests is known as a coagulation study. Individually these tests are commonly referred to as a prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR).
After taking into consideration the differences across the general population, the INR ranges between 0.8 and 1.2 among them. This indicates that in most instances, the blood will clot in thirteen seconds on conducting the test. High PT INR values. A high INR value generally indicates an increased risk of bleeding.
International Normalized Ratio (INR): International Normalized Ratio (INR), also known as Prothrombin Time (PT normal) is a system for reporting the results of blood coagulation tests. INR calculation is based on the results of PT test that is used to monitor treatment with the blood-thinning medication warfarin.

ent ways of reporting the prothrombin time across the world.8 Inappropriate management can lead to subtherapeutic or supratherapeutic INR values, increasing the risk of acute or recurrent thromboembolic episodes or bleed-ing episodes, respectively. For most indications, the therapeutic INR range is 2.0 to 3.0. Exceptions are when war-
