Although the normal platelet count in humans (150 to 400 × 109/L) far exceeds the minimal level required to avoid pathologic hemorrhage (<50 × 109/L), a number of medical conditions either increasing the destruction of platelets or reducing their production, enhance the risk of bleeding. This chapter discusses an approach to the diagnosis of thrombocytopenia, grouping various causes by mechanism of action, and describing our current understanding of the pathogenesis, treatment and prognosis. In the vast majority of patients, a cause for thrombocytopenia can be identified, and effective therapy instituted.
