Patient's question:
What blood type can women with type O blood have children with to avoid causing hemolytic disease of the newborn?Doctor's answer:
Hemolytic disease of the newborn primarily depends on the blood types of the mother and the fetus. ABO hemolytic disease mainly occurs when the mother is type O and the fetus is type A or B. If the mother is type AB or the baby is type O, hemolytic disease of the newborn will not occur. Moreover, approximately 40-50% of ABO hemolytic disease occurs in the firstborn. It is recommended that both partners undergo medical examination together before pregnancy.
