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.
To reduce this risk, an Rh-negative pregnant woman may be given injections of Rh immunoglobulin (RhIg). The injections are given at about 28 weeks in the pregnancy and immediately after delivery. With these injections, Rh-negative women can have safe Rh-positive pregnancies.
