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.
The INR has basically replaced the prothrombin time, or PT.
prothrombin time, hematocrit
prothrombin time
It decreases synthesis of thromboxane A2 and prostaglandins to increase bleeding time. It does not affect PT or PTT. Prothrombin time unaffected!

Vitamin K corrects prothrombin in the setting of biliary obstruction but not of hepatocellular damage.
Prothrombin time (PT) measures the activity of coagulation factors in the tissue factor pathway of the coagulation cascade.
