This test measures a substance called parathyroid hormone (PTH) in your blood. PTH is made by four tiny parathyroid glands in your neck. PTH circulates in your blood and is needed to regulate the level of calcium in your blood.
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. Other things to know: 1  Some patients take a drug called Coumadin (warfarin), which elevates the PT for the purpose of thinning the blood. 2  The test called INR measures the same factors as PT and is used instead of PT by many doctors.
