Prothrombin time (PT) and activated partial thromboplastin time (APTT) are tests that evaluate the release of specific clotting factors by measuring the time it takes for a clot to form after certain reagents are added to a blood sample.

There are various ways to test PT and because of the differences of testing methods used by laboratories, INR or international normalized ratio is used to standardize the PT test results.T refers to prothrombin time, a type of blood test that measures a personâs blood clotting time.
