<prompt> Marker for intrinsic pathway is:Prothrombin Time PTBleeding time BTClotting time CTActivated paial thromboplastin time aPTT  <response>: 1.The Activated paial thromboplastin time PTT assay screens the function of the proteins in the intrinsic pathway factors XII, XI, IX, VIII, X, V, II, and fibrinogen. 2. Prothrombin time - Assay assesses the function of the proteins in the extrinsic pathway factors VII, X, V, II, and fibrinogen. 3.Bleeding time - It indicates the functioning of the platelets. 4.Clotting time - It is altered in the patients who are having either a defect in the platelets or there is a defect in the clotting factors.
