![]() ![]() A needle is used to draw blood from a vein in your arm or hand. Healthcare providers usually want the INR to be between 2.0 and 3.0 for people on a blood thinner, such as warfarin. This is called the International Normalized Ratio (INR). If you have this test because you are taking an anticoagulant, such as warfarin, the result is often reported as a number that compares your result with that of a standard value. If your blood does not clot within that normal range, you may have a clotting or bleeding disorder. The normal clotting time is typically between 11 and 13 seconds. This test result is often reported in seconds. Ask your healthcare provider what your test results mean for you. Your test results may be different depending on the lab used. Test results may vary depending on your age, gender, health history, and other things. Other tests that measure aspects of blood clotting, such as platelet function You may need other tests that measure the ability of your blood to clot normally. What other tests might I have along with this test? This is to help make sure your blood is clotting normally so you don’t have problems with bleeding after the surgery or procedure. You may also need this test before you have surgery or a procedure. This is to help make sure you are taking the right dose. You may need this test regularly if you are taking a blood thinner, such as warfarin. You may need this test if you have symptoms of a bleeding disorder. These include:ĭeficiency in clotting factor I, II, V, VII, or X The test may be used to help diagnose inherited disorders and other conditions that may affect blood clotting. If the prothrombin doesn't change as quickly as normal, you may have a blood clotting disorder. The prothrombin time test measures how quickly prothrombin changes to thrombin to stop the bleeding. When bleeding occurs in the body, prothrombin quickly changes to thrombin. Prothrombin is one type of clotting factor. ![]() Problems in the blood, such as low levels of clotting factors or platelets, can keep blood from clotting normally and cause too much bleeding.Ĭlotting factors are usually made by the liver. The platelet cells and clotting factors then react to thicken the blood and stop the bleeding. They change it from a liquid to a solid.Īs soon as you start to bleed somewhere in or on your body, platelet cells in the blood collect around the bleeding area. Proteins in the blood called clotting factors (coagulants) help blood become sticky and clot. Blood clotting (coagulation) is needed to help stop bleeding. The prothrombin time is 1 of several tests that check if your blood is clotting normally. Prothrombin time/PT, Pro time, Prothrombin time/International normalized ratio, PT/INR What is this test? Prothrombin Time Does this test have other names? ![]()
