Question

Quizplus · Accepted Answer

The activated partial thromboplastin time (aPTT) evaluates the intrinsic coagulation pathway and is used to monitor heparin therapy. Bleeding time evaluates the primary hemostatic plug, prothrombin time evaluates the extrinsic and common pathways, and fibrin split products are breakdown products of fibrin and not a test of coagulation.
