Q

If an Rh- mother becomes pregnant with an Rh+ baby and it is her first pregnancy, is that baby at risk for developing hemolytic disease of the newborn (also called erthroblastosis fetalis)?

A

No. The Rh+ child’s blood doesn’t mix with the Rh- mother’s blood until childbirth. By the time the Rh- mother makes Anti-D (Rh) antibodies the Rh+ child has been born and is no longer in the uterus.

Q

An Rh- mother becomes pregnant with an Rh+ baby and it is her first pregnancy. The child is not at risk for developing hemolytic disease of the newborn because by the time the mother makes anti-D antibodies, the Rh+ child has been born. If the SAME Rh- mother becomes pregnant with another Rh+ baby, is that baby at risk for developing hemolytic disease of the newborn (also called erthroblastosis fetalis)?

A

Yes. The antibodies against the Rh factor (anti-D/Rh) made in response to her body being exposed to the D antigen during the first childbirth will cross the placenta and attack (bind to and agglutinate) the red blood cells of the second Rh+ baby.
