The authors have stressed the need to distinguish between simple thrombocytopenia and disseminated intravascular coagulation (DIC) when bleeding occurs in relation to an infectious disease such as chickenpox. In the former condition, only thrombocytopenia will be found with no anemia unless significant blood loss has occurred. Measurements of plasma clotting factors will all have normal values. The bone marrow sample will have normal-to-increased numbers of megakaryocytes in response to the rapid platelet destruction.
