And even in the uncommon deliveries where it is a problem, doctors can administer a blood transfusion. Problems from ABO incompatibility will occur only after the delivery. If they can’t get into the baby’s blood, then there’s no way for them to attack the unborn baby. These ABO group antibodies are too large to cross the placental barrier and get into the baby’s blood. The mother’s immune system will then create special antibodies that attack the ABO group of the baby’s blood cells, just like in Rh incompatibility.īut these antibodies are different than the antibodies that attack the Rh proteins! In situations where a mother has Type O blood, and the baby has A, B, or AB blood, the mother’s immune system will recognize the baby’s blood as foreign. Unlike Rh incompatibility, ABO incompatibility during pregnancy is rarely a problem - even when the mother’s ABO group doesn’t match the baby’s ABO group! With RhoGAM, we don’t have to worry about Rh incompatibility during pregnancy anymore. Now the unborn baby’s blood cells are protected. Without these cells present, the mom’s immune system won’t develop the antibodies that attack the baby’s blood cells. Basically, the RhoGAM absorbs all the Rh+ cells released from the baby. These shots prevent the mother's immune system from harming the baby. The first one is given around the 28th week of pregnancy, and another just after birth.

If there is a risk of Rh incompatibility, doctors will give a series of RhoGAM shots during pregnancy. Luckily, the medical community found a solution to this back in the 1960s. This is referred to as Rh disease of the newborn. It takes some time for the mom to make these antibodies, so these antibodies are not usually an issue during the first pregnancy.īut in future pregnancies, if the mom’s immune system sees any Rh proteins, they are treated like foreign invaders! It will attack any Rh+ blood cells, even those of the mom’s own unborn baby. Later after birth, the Rh- mom’s immune system will create antibodies that will attack any Rh+ blood they see in the future. The mom’s immune system will think these definitely don’t belong – her own blood cells don’t have Rh! In a mom that is Rh-, her immune system won’t recognize the Rh+ in the baby’s blood. But it can lead to problems in later pregnancies.ĭuring birth, the blood of mother and baby will mix. This mismatch doesn’t cause any problems for the first pregnancy. This mismatch in blood type is often referred to as Rh incompatibility.
Problems can occur when the mother is Rh- and the baby is Rh+. Usually there’s nothing to be worried about, though a few exceptions are talked about below. Usually when planning to have a child, the doctor will take a look at the blood groups of both parents to decide if there’s any risk during the pregnancy. There are two main blood groups:įor more on how these are inherited, see this article on ABO type or this article on Rh type. There are 8 main blood types: A+, A-, B+, B-, AB+, AB-, O+, or O-.Ī person’s blood type is determined based on the decorations that surround their blood cells.
In particular, an Rh negative mother can sometimes have pregnancy complications - though doctors have an easy way to fix this issue! Blood Type Usually, we don’t have to worry about blood type when deciding to have a child.
