Hemolytic disease of the newborn or erythroblastosis fetalis occurs when there is an incompatibility between the blood types of the mother and baby. In this condition, red blood cells of the newborn are broken down and destroyed (hemolysis). When the red blood cells break down, a substance called bilirubin is formed. The Bilirubin has a pigment or coloring, it causes a yellowing of the baby's...
