Prothrombin time in seconds Prothrombin time is usually measured in seconds ie, the time it takes for your blood to clot. The results of the prothrombin test vary depending on the laboratory, the test chemicals used in different laboratories and the method used to test blood. What do your PT test results mean? A number higher than average means it takes blood longer than usual to clot. A lower number means blood clots more quickly than expected.
A prolonged PT means that the blood is taking too long to form a clot. This may be caused by conditions such as liver disease, vitamin K deficiency, or a coagulation factor deficiency. Prothrombin time as a ratio — INR Because the results of the prothrombin time test vary from laboratory to laboratory, a ratio called the international normalised ratio INR is calculated.
Prothrombin Time and INR
The INR is a formula that allows for differences in different laboratories so that test results can be compared. What do your INR results mean? For people taking warfarin, the INR target range will be different for different people, depending on the condition for which the warfarin is being prescribed.
In most situations, the target INR is between 2 to 3. For some who have a high risk of a blood clot, the INR needs to be higher — about 2. If your INR is above the target range, this means that your blood is clotting too slowly and you are at risk of bleeding.
If your INR is below the target range, this means that your blood is clotting more quickly than ideal for people on warfarin and you may be at risk of unwanted clots being formed. The absence of any of the clotting factors. Other substances, called inhibitors, that affect the clotting factors. An increase in the use of the clotting factors.

Prothrombin levels are checked along with other liver tests, such as aspartate aminotransferase and alanine aminotransferase.
