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.
For this test, a sample of your blood is collected in a vial. Chemicals are then added to the blood. The test results are based on how many seconds it takes for your blood to clot after the chemicals are added. This test is sometimes called an activated partial thromboplastin time (APTT) test.
