A full-term 5-day-old African-American girl is taken to the pediatrician because her “eyes look yellow.” She is being exclusively formula-fed with an iron-rich formula. She has six wet diapers a day and stools twice a day. The pregnancy was uncomplicated and she was delivered by spontaneous vaginal delivery. Her Apgar scores were 9 and 10 at 1 and 5 minutes, respectively. Her temperature is 37°C (98.6°F), her head circumference is in the 50th percentile, and her weight is 3420 g (3 g below her birth weight). Her sclerae are icteric. There is no hepatomegaly or splenomegaly. Her total bilirubin is 9 mg/dL and her conjugated bilirubin is 0.2 mg/dL. Hemoglobin is 15 g/dL. Which of the following is the most likely diagnosis?
(A) α1-Antitrypsin deficiency
(B) Biliary atresia
(C) Dubin-Johnson syndrome
(D) Physiologic jaundice
(E) Rotor syndrome
