Bilirubin is a pigment in the blood, urine, and bile that results from the normal breakdown of hemoglobin in the red blood cells. High levels of bilirubin in a baby is called “jaundice.”
A birth defect, also known as a congenital disorder, is a problem that happens while the baby is developing in the mother’s body. It may affect how the body looks, works or both. It can be found before birth, at birth, or anytime after birth. Birth defects can vary from mild to severe.
