Prothrombin Time (PT) Test
Overview
The PT test measures the time it takes for a clot to form in your blood. It measures the effectiveness of of the extrinsic and common pathways of your blood clotting cascade that includes vitamin K dependent clotting factors. Prothrombin is a protein made by your liver that plays an important role in clotting. The PT test indirectly assesses the function of prothrombin and other clotting factors that play an important role in this particular pathway. This test is used by doctors to track the effectiveness of blood thinners (like warfarin), to diagnose blood or clotting problems, and to evaluate liver function (because the liver makes clotting factors).
