Prothrombin is another protein produced in your liver. The prothrombin time (PT) test measures how well and how long it takes your blood to clot. It normally takes about 25 to 30 seconds. It may take longer if you take blood thinners. Other reasons for abnormal results include hemophilia, liver disease, and malabsorption.
The prothrombin time is made longer by: 1  Blood-thinning medicine, such as warfarin. 2  Low levels of blood clotting factors. 3  A change in the activity of any of the clotting factors. 4  The absence of any of the clotting factors. 5  Other substances, called inhibitors, that affect the clotting factors. 6  An increase in the use of the clotting factors.
