To determine your baby’s blood type, a blood test needs to be conducted. The ABO and Rh blood type of both parents will be analyzed to determine the potential blood type of the baby.

Determining a baby’s blood type is an important step in understanding their genetic health and potential risks for certain conditions. While it is not possible to determine a baby’s blood type without conducting a blood test, there are specific factors that can help determine the potential blood type of the baby based on the parents’ blood types.
To determine the potential blood type of a baby, the blood types of both parents need to be analyzed. Blood types are determined by the presence or absence of specific antigens on the surface of red blood cells. The two most common blood typing systems are the ABO system, which categorizes blood types as A, B, AB, or O, and the Rh system, which categorizes blood types as Rh positive or Rh negative.
When it comes to the ABO system, there are four possible blood types that a baby can inherit from their parents: A, B, AB, or O. Each parent contributes one allele, or variant of a gene, to determine the baby’s blood type. Here’s a breakdown of the potential blood types the baby can have:
- If both parents have blood type A, the baby can have blood type A or O.
- If both parents have blood type B, the baby can have blood type B or O.
- If one parent has blood type A and the other has blood type B, the baby can have blood type A, B, AB, or O.
- If one parent has blood type A and the other has blood type AB, the baby can have blood type A, B, or AB.
- If one parent has blood type A or B and the other has blood type O, the baby can have blood type A or B.
- If one parent has blood type AB and the other has blood type O, the baby can have blood type A or B.
Furthermore, the Rh factor plays a role in determining the potential blood type of the baby. A positive Rh factor is dominant, meaning if either parent is Rh positive, the baby will likely be Rh positive. However, if both parents are Rh negative, the baby will also be Rh negative.
To illustrate the potential blood type combinations, here is a table outlining the possible outcomes based on the parents’ blood types:
| Mother’s Blood Type | Father’s Blood Type | Potential Baby’s Blood Type |
|---|---|---|
| A | A | A, O |
| B | B | B, O |
| A | B | A, B, AB, O |
| A | AB | A, B, AB |
| A or B | O | A, B |
| AB | O | A, B |
In conclusion, determining a baby’s blood type relies on conducting a blood test that analyzes the ABO and Rh blood types of both parents. Understanding the potential blood type of your baby can provide valuable insights into their genetic health and potential risk for certain conditions.
As the famous physician and geneticist James D. Watson once said, “DNA itself is not a blueprint; it is a script. And it is the active players, proteins …, that tip the scales, moving genes up or down. Moreover, a gene may produce multiple products, depending on what is happening in the cell at the time.” This quote emphasizes the complexity of genetics and the importance of exploring the information encoded in our DNA to understand various aspects of our health, including blood types.
Interesting facts about blood types:
- Blood types are inherited from parents and are determined by specific genes.
- Approximately 85% of people are Rh positive, while the remaining 15% are Rh negative.
- The rarest blood type in the world is AB negative, with fewer than 1% of people having this blood type.
- Blood type O negative is considered the universal donor, as it can be given to individuals of any blood type.
- People with blood type AB positive are considered universal recipients because they can receive blood from any blood type.
- Blood types can play a role in compatibility for blood transfusions and organ transplants.
- Some studies suggest that certain blood types may be more susceptible to certain diseases, but more research is needed to establish concrete relationships.
Remember, when it comes to determining your baby’s blood type, consulting with a healthcare professional and conducting a blood test are the most accurate ways to obtain this information.
Answer to your inquiry in video form
This video on the inheritance of blood types explains various scenarios based on the blood types of parents. If one parent has blood type A and the other has blood type O, all the children will be blood type A. However, if the parent with type A is heterozygous, half of the children will be type A and the other half will be type O. A similar inheritance pattern applies to blood type B and O. Additionally, it is mentioned that if an individual receives one allele for blood type A and one allele for blood type B, they will have both blood type A and B, as the alleles for these blood types do not counteract each other.

The ABO test is a common blood type test. The ABO test shows which of four blood types your child has: A, B, AB, or O. These letters stand for which kind of antigen is on your child’s red blood cells. If your child’s red blood cells don’t have either the A or B antigen, your child has type O blood.
How can I find out my child’s blood type? Ask your parents or doctor They may know or have old health records that include your blood type. You can also reach out to your healthcare provider, who may have that information on file.
Our blood type calculator can help you discover it! A baby’s probable blood group is mainly determined by the mother and the father’s genes (1). While knowing the exact blood group of the unborn baby is not possible, this tool gives you a list of the blood types that baby likely to have. Select the mother’s and the father’s blood type and you can find out the probable blood group of your child.
Blood type tests are used to check what blood type your child has. Blood is "typed" according to whether certain markers, called antigens, are on the surface of red blood cells. The ABO test is a common blood type test. The ABO test shows which of four blood types your child has: A, B, AB, or O.
You can find out your blood type by asking your doctor for a test, donating blood, or taking an at-home blood test. Your blood type is comprised of two blood groups: ABO and Rh. Blood types are based on antigens on the surface of your red blood cells. An antigen is a substance that triggers an immune response by your body against that substance.
Here’s how to find out yours
- Ask your parents or doctor Before you go out of your way to try any of the other methods, check with your parents first.
- Blood draw Next time you go in to get your blood drawn, ask to know your blood type.
