Overview
Bleeding diathesis is unusual susceptibility to bleed due to hypo-coagulopathies. These diseases can occur due to a disorder of homeostasis, localized process (tissue injury), or medications. Bleeding diathesis can be resulted from vessel wall injury, platelet disorders, and coagulation factor disorders. Clinical manifestation of bleeding disorders can have a wide range of symptoms from asymptomatic to symptomatic massive and life threatening bleeding. Platelet disorders mostly have skin manifestations such as petechiae, and ecchymoses. In order to find the cause of hypo-coagulopathy, there are established laboratory tests that might be used. These laboratory tests such as peripheral blood smear, platelet count and platelet function analysis, coagulation factor deficiencies and inhibitors, fibrinolysis tests (eg. D-dimer level), bleeding time, prothrombin time, activated partial thromboplastin time, thrombin time and reptilase time.
