During any pregnancy a small amount of the baby's blood can enter the mother's circulation. If the mother is Rh negative and the baby is Rh positive, the mother produces antibodies (including IgG) against the Rhesus D antigen on her baby's red blood cells.
In some cases, the baby's father might need an Rh factor test, too. During pregnancy, problems can occur if you're Rh negative and the baby you're carrying is Rh positive. Usually, your blood does not mix with your baby's blood during pregnancy. However, during delivery or certain times during pregnancy, a small amount of your baby's blood could come in contact with your blood.
