As a new mom, you’re full of so many questions. One of the big ones is when your baby will develop ABO antibodies. These antibodies are important for your baby’s health, so it’s essential to know when they’ll start to develop. In this blog post, we’ll go over everything you need to know about when your baby will develop ABO antibodies.

What Are ABO Antibodies?
First, let’s break down what ABO antibodies are. These antibodies are proteins that your body produces to fight against foreign cells. In the case of ABO antibodies, they are produced in response to different blood types. There are four major blood types: A, B, AB, and O. If you have type A blood, your body produces A antibodies. If you have type B blood, your body produces B antibodies. If you have type AB blood, your body produces both A and B antibodies. If you have type O blood, your body does not produce A or B antibodies.
When Do Babies Start Developing ABO Antibodies?
When it comes to babies, they start developing ABO antibodies in the womb. This process is called sensitization. If a baby has a different blood type than their mother, their mother’s body may produce antibodies against their baby’s blood type. This can happen if the baby’s father has a different blood type than the mother or if the baby inherited a different blood type from another family member.
Sensitization can happen as early as 12 weeks into pregnancy, but it’s more common later in pregnancy. It’s important to note that sensitization only happens if the baby’s blood type is different from the mother’s. If the baby has the same blood type as the mother, sensitization will not occur.
What Happens If A Baby Is Sensitized?
If a baby is sensitized, it means that their mother’s body has produced antibodies against their blood type. These antibodies can cross the placenta and attack the baby’s red blood cells. This can lead to a condition called hemolytic disease of the newborn (HDN). HDN can cause jaundice, anemia, and even brain damage or death if left untreated.
How Can Sensitization Be Prevented?
The best way to prevent sensitization is to determine the baby’s blood type and the mother’s blood type early in pregnancy. If the baby has a different blood type, the mother can receive an injection of Rh immunoglobulin (RhIg) around 28 weeks of pregnancy. This injection can prevent sensitization by blocking the mother’s body from producing antibodies against the baby’s blood type.
It’s important to note that RhIg only works for Rh sensitization. It does not prevent ABO sensitization. If the mother has type O blood and the baby has a different blood type, there is no way to prevent sensitization. However, ABO sensitization is less severe than Rh sensitization and usually does not cause HDN.
Conclusion
In conclusion, babies start developing ABO antibodies in the womb through a process called sensitization. Sensitization can happen as early as 12 weeks into pregnancy, but it’s more common later in pregnancy. If a baby is sensitized, it can lead to HDN, which can cause serious health problems. However, sensitization can be prevented through early blood typing and RhIg injections if necessary. If you have any concerns about ABO antibodies or sensitization, talk to your healthcare provider for more information.
