WebThe 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. WebThe Prothrombin Time (PT) test is an in-vitro laboratory test used to assess the extrinsic or tissue factor dependent pathway. The test also evaluates the common coagulation pathway involving all the reactions that occur after the activation of factor X.
