A 2-year-old child was tested for blood lead level. The result was 25 mcg/dL. He also had microcytic, hypochromic anemia. The child's parents were questioned, and it was determined that the source of lead was a painted crib in his day care center. The child was enrolled in another day care center. Follow-up testing revealed that the blood lead level was within normal limits but the microcytic, hypochromic anemia was still present. Which follow-up test(s) would you recommend to help identify the etiology of this anemia? (Objectives 9,14,15)
A) serum iron, serum ferritin, TIBC, % saturation
B) hemoglobin electrophoresis
C) molecular diagnostic testing for sideroblastic anemia
D) molecular diagnostic testing for hemosiderosis
