- Actually, it is the opposite. An X+ father and an X- mother may produce an
- X+ child. During delivery the mother is often exposed to the baby's blood,
- and develops anti-Rh agglutinins. In subsequent pregnancies , these
- agglutinins cross the placenta. If the baby is X-, there is no problem. If
- the baby is X+, the agglutinins cause hemolysis (rupture) of the red blood
- cells, making the baby unable to carry oxygen in its blood. To treat this,
- the baby's blood is slowly removed after birth and replaced with Rh- blood.
- The mother can be treated after her first delivery (or after abortion or
- miscarriage), though, with anti-Rh gamma2-globulin which ties up the anti-Rh
- agglutinins. This syndrome is known as erythroblastosis fetalis or hemolytic
- disease of the newborn.
