What medical condition would a baby be suffering from if the mother is Rh-negative and the baby is Rh positive?
Rh incompatibility develops only when the mother is Rh-negative and the infant is Rh-positive. This problem has become less common in places that provide good prenatal care. This is because special immune globulins called RhoGAM are routinely used.
What complications may occur when an Rh-negative mother is carrying an Rh positive fetus?
If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign. Her antibodies will pass into the baby's bloodstream and attack those cells. This can make the baby's red blood cells swell and rupture.

During pregnancy, some fetal blood cells may occasionally escape into the mother’s circulation, exposing her to potentially Rh positive blood cells. If this occurs, an Rh negative mother’s immune system will recognize these cells as foreign and produce antibodies against them called anti-D antibodies.
What is RhoGAM?
Rho (D) Immune Globulin, also known as RhoGAM, is a preparation of anti-D antibodies that recognize the “D” antigen as foreign. When this preparation is given to an Rh negative mother it coats Rh positive fetal blood cells in her circulation resulting in their destruction before the mother can produce her own antibodies against them.
Alloimmunization: What then?
In spite of the availability of RhoGAM to Rh negative women, 0.1 to 0.2 percent of Rh negative patients still become sensitized to an Rh positive baby and develop anti-D antibodies. These anti-D antibodies pose a risk to future pregnancies since they may attack an Rh positive fetus.
Conclusion
For Rh negative mothers, the old addage “an ounce of prevention is worth a pound of cure” is appropriate. It is important for Rh negative mothers to receive RhoGAM administration at the appropriate times during pregnancy to avoid the occurrence of alloimmunization.

Why does a woman have more antibodies?
This is because her body does not have a chance to develop a lot of antibodies. But if treatment is not given during the first pregnancy and the woman later gets pregnant again with an Rh-positive fetus, she can make more antibodies. More antibodies put a future fetus at risk.
