CBC and RBC Morphology

CBC results for patients with double heterozygous condition of sickle cell with beta thalassemia (Hb S/Bthal) can be asymptomatic or demonstrate a slight to moderate anemia. The CBC and peripheral blood smear for a patient with Hb S/Bthal, which appear below, reflect results more consistent with thalassemia than hemoglobinopathy. The hemoglobin electrophoresis results on the following page revealed this condition.

Reference intervals may vary between facilities and are dependent on patient age and gender. The reference intervals that are shown below are specific to this case.
