Are You At Risk For A Blood Clot? |  Check

6) Check your own PT/INR levels. This blood test is important to your healthcare wellness check, because it checks the coagulation factor for patients taking blood thinner medication, such as, Coumadin or Warfarin.  It tests how thin or how thick your blood serum may be.  The prothrombin time is one of several blood tests that evaluate whether your blood is clotting properly. Blood clotting, or coagulation, is needed to help stop bleeding.  Proteins in the blood called clotting factors or coagulants help blood become sticky and clot.  They change it from a liquid to a solid.  As soon as you get a cut or the body starts to bleed, platelet cells in the blood collect around the bleeding area.  The platelet cells and clotting factors then react to thicken the blood and stop the bleeding.  Abnormalities in the blood, including deficiencies in clotting factors or platelets, can prevent blood from clotting normally and cause abnormal bleeding.

Clotting factors are usually produced by the liver. Prothrombin is one type of clotting factor. When bleeding occurs somewhere in the body, prothrombin quickly changes to thrombin. The prothrombin time test measures how quickly prothrombin changes to thrombin to stop the bleeding. If the prothrombin doesn't change as quickly as normal, a blood clotting disorder could be the cause.

The prothrombin time blood test can find a lack of certain coagulants if the blood does not clot normally. The prothrombin time test may be used to help diagnose inherited disorders and other conditions that may affect blood clotting.

These include:

Vitamin K deficiency

Deficiency in clotting factor I, II, V, VII, or X

Diseases of the liver


Problems with the bone marrow

Von Willebrand disease

Problems with the immune system

Some types of cancer, including leukemia
