WebApr 5, 2016 · Both the intrinsic and extrinsic pathways lead to factor 10, which is the start of the common pathway. The two key players in the common pathway are thrombin and fibrin. Fibrin is the most important part of the clotting cascade because fibrin is what traps the platelets, and is therefore clotting factor number 1. WebJan 6, 2016 · aPTT/PTT testing is used to assess if the intrinsic pathway is intact. Blood is drawn and coagulation time is calculated in the absence of tissue factor (which is why it can assess the intrinsic pathway). An activator (like silica) is used to set off the intrinsic clotting factor cascade. Reference range: 30-50 sec. PROTHROMBIN TME (PT)
