How do you do a PT test?
What does a high PT mean?
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 is normal PT?
Normal Results PT is measured in seconds. Most of the time, results are given as what is called INR (international normalized ratio).
