What is the most common type of ABO incompatibility in neonates?

ABO incompatibility can occur between the mother and fetus under three scenarios. The blood types are: A, B, and O. The most common incompatibility occurs when the mother has O type blood and the fetus has B, A, or AB.

What blood type causes ABO incompatibility?

ABO incompatibility happens when a mother’s blood type is O, and her baby’s blood type is A or B. The mother’s immune system may react and make antibodies against her baby’s red blood cells. The consequences and treatment are similar to Rhesus disease.

Can certain blood types not have babies together?

Although your blood and your baby’s blood typically do not mix during pregnancy, a minimal amount of your baby’s blood and your blood could come in contact with each other during delivery. If there’s an Rh incompatibility and this happens, your body might produce Rh antibodies against Rh factor.

What is neonatal ABO incompatibility?

In the case of neonatal ABO incompatibility, a mother with blood type O will have antibodies against A and B antigens. If those antibodies reach the baby’s system, they can destroy baby’s red cells in cases where there are antigens A or B on those cells (baby with blood type A, B, AB).

What is ABO blood type incompatibility?

In that case, he could be at risk for a condition known as ABO blood type incompatibility, a type of illness known as a hemolytic disease of the newborn (HDN). 1  (Another example of an HDN occurs when a mother’s blood is Rh-negative and her baby is Rh-positive.

Is it possible to have a baby with different blood types?

Not all non-matching combinations of blood types are problematic. ABO incompatibility can occur only if a woman with type O blood has a baby whose blood is type A, type B, or type AB. If a baby is type O there won’t be a problem with a negative immune response because type O blood cells don’t have immune-response triggering antigens.

What are the most common problems caused by ABO incompatibility?

The most common problem caused by ABO incompatibility is jaundice. Jaundice occurs when there’s a buildup of an orangish-red substance in the blood called bilirubin that’s produced when red blood cells break down naturally.
