Laboratory evaluation of a bleeding patient.
Most causes of abnormal bleeding can be determined from a complete blood count including platelet count and bleeding, prothrombin, activated partial thromboplastin, and thrombin times. Occasionally, further evaluation is necessary, such as tests of factor XIII function, fibrinolysis, and vascular integrity. Possible diagnoses include disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, vitamin K deficiency, von Willebrand's disease, heparin-induced thrombocytopenia, acquired inhibitors of factor VIII, lupus anticoagulants, and coagulation disorders related to the acquired immunodeficiency syndrome.
