What Is a High Pt Level

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 a good PT level?

Normal Results PT is measured in seconds. Most of the time, results are given as what is called INR (international normalized ratio). If you are not taking blood thinning medicines, such as warfarin, the normal range for your PT results is: 11 to 13.5 seconds. INR of 0.8 to 1.1.

What can cause a high PT level?

• Blood-thinning medications.
• Liver problems.
• Inadequate levels of proteins that cause blood to clot.
• Vitamin K deficiency.
• Other substances in your blood that hinder the work of clotting factors.
