How is approach to autoimmune hemolytic anemia?

Standard blood studies for the workup of suspected hemolytic anemia include the following: ➢ Complete blood cell count ➢ Serum lactate dehydrogenase (LDH) study ➢ Serum haptoglobin ➢ Indirect bilirubin ➢ Peripheral blood smear (Peripheral smear findings can help in the diagnosis of a concomitant underlying hematologic malignancy associated with hemolysis.) Other laboratory studies may be directed by history, physical examination, peripheral smear, and other laboratory findings. (DAT, free hb, red blood cell survival, cold agglutinin, G6PD)
