Webb15 feb. 2024 · The PT/INR and APTT are the most commonly measured screening tests to assess a patient's coagulative state. Prothrombin time (PT) is a test of the extrinsic and common pathways including factors VII, V, X, II and fibrinogen. It is performed by adding calcium and thromboplastin to a plasma sample and measuring the time to clot. WebbThe cascade has two initial pathways: the extrinsic (tissue factor-mediated) and the intrinsic (contact system-initiated). These two pathways converge to become the common pathway with the activation of factor X. The steps in the cascade that are measured by the three common coagulation assays, PT, aPTT, and TT, are indicated.
