Thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome may be a cause of anemia. Hereditary spherocytosis either may present as a severe hemolytic anemia or may be asymptomatic with compensated hemolysis. Similarly, glucose-6-phosphate dehydrogenase (G-6-PD) deficiency may manifest as chronic hemolytic anemia or exist without anemia until the patient receives an oxidant medication. Immunologic etiologies for anemia may include antibody-mediated abnormalities. In the emergency department (ED), acute hemorrhage is by far the most common etiology for anemia.
