Prothrombin time (PT) is a blood test that measures how long it takes for blood to clot, specifically assessing the extrinsic and common pathways of coagulation. It is significant for diagnosing bleeding disorders, monitoring patients on anticoagulant therapy (such as warfarin), and evaluating liver function, as the liver produces many proteins involved in clotting. Prolonged PT can indicate various conditions, including vitamin K deficiency, liver disease, or the presence of certain anticoagulants. Regular monitoring of PT helps guide treatment decisions and ensure patient safety.
