A 3010-g (6.6-lb) boy was born to a 37-year-old primagravida by spontaneous vaginal delivery after an uncomplicated pregnancy. On examination he has cyanotic extremities and a significant right precordial heave, a single S2, and a harsh systolic ejection murmur along the sternal border. He also has a prominent squared nose and cleft palate. An echocardiogram is subsequently performed and demonstrates tetralogy of Fallot. Corrective surgery is performed without complications. At 2 months of age the infant is diagnosed with Pneumocystis jiroveci pneumonia, and at 3 months he is diagnosed with fungal septicemia. Additional work- up of this child should include which of the following tests?
(A) Hemoglobin electrophoresis
(B) Nitroblue tetrazolium
(C) Quantitative immunoglobulin levels
(D) Renal ultrasound
(E) Serum calcium
