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.
Prothrombin time (PT) measures the presence and activity of five different blood clotting factors (factors I, II, V, VII, and X). This test measures the integrity of the extrinsic and common pathways of coagulation. The prothrombin time (PT) measures the clotting time from the activation of factor VII through the formation of the fibrin clot.
