If your baby is born Rh negative, no additional treatment is needed. The immune globulin prevents your body from producing Rh antibodies during your pregnancy. If you haven't started to produce Rh antibodies, you'll likely need an injection of a blood product called Rh immune globulin.
The antibody screen is used to detect antibodies to Rh positive blood. If you're Rh negative, you might need to have another blood test - an antibody screen - during your first trimester, during week 28 of pregnancy and at delivery. Red blood cells are needed to carry oxygen throughout the body. This could lead to life-threatening anemia, a condition in which red blood cells are destroyed faster than the baby's body can replace them. If your next baby is Rh positive, these Rh antibodies can cross the placenta and damage the baby's red blood cells. The antibodies produced aren't a problem during the first pregnancy. If you're Rh negative and your baby is Rh positive, your body might produce proteins called Rh antibodies after exposure to the baby's red blood cells.
However, a small amount of your baby's blood could come in contact with your blood during delivery or if you experience bleeding or abdominal trauma during pregnancy. Usually, your blood doesn't mix with your baby's blood during pregnancy. During pregnancy, problems can occur if you're Rh negative and the baby you're carrying is Rh positive.
