What does protime measure?

The prothrombin time, sometimes referred to as PT or pro time test, is a test to evaluate blood clotting. Prothrombin is a protein produced by your liver. It is one of many factors in your blood that help it to clot appropriately.

What does it mean if your protime is high?

When the PT is high, it takes longer for the blood to clot (17 seconds, for example). This usually happens because the liver is not making the right amount of blood clotting proteins, so the clotting process takes longer. A high PT usually means that there is serious liver damage or cirrhosis.

What causes PT INR to be high?
