Other factors may also be responsible for reduced blood clotting. PT test is not an absolute test for determining the risk of excess bleeding. Results in these ranges mean that blood is clotting within a standard time range and the concentration of functional prothrombin in blood is appropriate. These values correspond to approximately 11-13.5 seconds (time taken by the blood to clot). Normal values for any individual can vary in the INR range 0.8-1.10. The test results can also be presented in seconds. PT test result is generally given in terms of international normalised ratio (INR) for standardisation across laboratories.
