title: Quantitative platelet disorders.
abstract: Thrombocytopenia may be caused by abnormal platelet production, accelerated removal owing to immunologic or nonimmunologic reasons, or sequestration of platelets in the spleen. Bleeding associated with thrombocytopenia usually presents as petechial or ecchymotic hemorrhages or epistaxis. Immunologic and nonimmunologic cases of thrombocytopenia may be diagnosed with routine hematology, bone marrow cytology, and platelet specific tests. Thrombocythemia may also be associated with platelet functional abnormalities, contrasting the normal platelet function noted in reactive thrombocytosis.
