What does a high prothrombin time indicate?
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 are the symptoms of high prothrombin time?
Bleeding or bruising easily. Blood clots that form when they shouldn’t. Blood in your poop or urine. Gums that bleed easily.
What is prothrombin time and when is it affected?
Prothrombin is one type of clotting factor. When bleeding occurs in the body, prothrombin quickly changes to thrombin. The prothrombin time test measures how quickly prothrombin changes to thrombin to stop the bleeding. If the prothrombin doesn’t change as quickly as normal, you may have a blood clotting disorder.
What drugs affect prothrombin time?
Drugs that increase or prolong the PT time include antibiotics, cimetidine (Tagamet), salicylates, and sulfonamides. Barbiturates, oral contraceptives, and Vitamin K in multivitamin preparations or in liquid nutritional supplements decrease the PT time.
What happens when prothrombin time is low?
If the prothrombin time (PT) is low, it means that when there is a hemorrhage the clot is formed very fast and the bleeding stops quickly. This may be positive, but it may be related to a hypercoagulable state where the blood clots too much and increase the risk of blood clot formation in veins.
What are the sources of error for the prothrombin time test?
The main sources of error include the patient’s biological and preanalytical variation, analytical testing, and postanalytical use of the reported result(s).

What does prothrombin time tell you?
The “prothrombin time” (PT) is one way of measuring how long it takes blood to form a clot, and it is measured in seconds (such as 13.2 seconds). A normal PT indicates that a normal amount of blood-clotting protein is available. When the PT is high, it takes longer for the blood to clot (17 seconds, for example).
What does high prothrombin time mean?
What does a high prothrombin time mean? A high prothrombin time (PT) in a blood test is a sign of a coagulation disorder. It means that it takes a long time for the blood to form a clot to stop a hemorrhage and therefore there is an excessive bleeding.
What is normal prothrombin time?
Your Prothrombin time level of 14 is a Normal Prothrombin time level. If your Prothrombin time is in between 12 seconds and 16 seconds, then you need not worry as 12-16 seconds is the normal range for Prothrombin time. But if your Prothrombin time is lesser or greater than the above values, then there may be some problem in your body.
