The blood group are of 4 types- A, B, AB, and O. Certain drugs, suppression or addition of an antigen in infection, bone marrow transplants, malignancy or autoimmune disease can cause the blood type to change from B to O.
Can you change your blood type to O?
Converting blood cells
A new study from the University of British Columbia reports that it’s possible to remove A and B antigens from blood cells, converting them to H antigens. That would stop A and B type blood triggering the dangerous immune response, so they could effectively become universal like type O.
Why blood type A and B can now be converted to blood type O?
One enzyme was found to be particularly effective at stripping away A antigens from red blood cells. What’s more, the researchers were able to combine their new enzyme with one that’s already known to remove B antigens from blood cells, providing a way to convert AB, A and B blood into type O.
Can a blood and B blood make an O baby?
And so is AB blood type. But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO.

| Genes | Blood type |
|---|---|
| BO | B |
| AB | AB |
| OO | O |
How common is it for your blood type to change?
Blood type generally does not change during lifespan. However, in some cases, blood type can change because of some disorders like autoimmune diseases and cancers. Disorders can happen at any age.
Can you convert blood types?
If a person with type A receives type B blood, or vice versa, these molecules, called blood antigens, can cause the immune system to mount a deadly attack on the red blood cells. But type O cells lack these antigens, making it possible to transfuse that blood type into anyone.
What are the 3 rarest blood types?
The rarest blood types are: B negative(B -ve), which is found in 1.5 percent of the total population. AB negative(AB -ve), which is found in 0.6 percent of the total population. AB positive(AB +ve), which is found in 3.4 percent of the total population.
What is golden blood type?
One of the rarest blood types in the world is Rhnull, sometimes referred to as ‘golden blood’. People with this blood type have a complete absence of any of the Rh antigens.
What is the rarest blood type?
AB negative
What’s the rarest blood type? AB negative is the rarest of the eight main blood types – just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don’t struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.
Do Babies always have the father’s blood type?
No it doesn’t. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent’s blood type.
How do you get O blood type?
How Is My Blood Type Determined? It’s inherited. Like eye color, blood type is passed genetically from your parents. Whether your blood group is type A, B, AB or O is based on the blood types of your mother and father.
How did I get O positive blood?
A person who is blood type O has to be genetically OO (receiving a gene that codes for neither A nor B from one parent and a gene that codes for neither A or B from another parent). The possible blood types of the parents include OO, AO, and BO.
What blood type should not have babies?
Usually, we don’t have to worry about blood type when deciding to have a child. However, there are some exceptions. In particular, an Rh negative mother can sometimes have pregnancy complications – though doctors have an easy way to fix this issue!
Which parent determines the blood type of the child?
The short answer: Both biological parents determine the baby’s blood type.
How do I find out my blood type without a test?
Ask your parents or doctor
Before you go out of your way to try any of the other methods, check with your parents first. 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.
Why O is universal donor?
For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it’s sometimes called the universal blood donor type.
Is O a good blood type?
Over 80% of the population has a positive blood type and can receive O positive blood. That’s another reason it’s in such high demand. O positive donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.
What happens if you mix blood types that are not compatible?
Transfusion with ABO incompatible blood can lead to severe and potentially fatal transfusion reactions. RhD is highly immunogenic and can lead to red cell haemolysis in certain settings.
What is the oldest blood type?
In molecular history, type A appears to be the ‘oldest’ blood type, in the sense that the mutations that gave rise to types O and B appear to stem from it. Geneticists call this the wild-type or ancestral allele.
Can siblings have different blood types?
Brothers and sisters don’t always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
Who has golden blood?
The golden blood type or Rh null blood group contains no Rh antigens (proteins) on the red blood cells (RBCs). This is the rarest blood group in the world, with less than 50 individuals having this blood group. It was first seen in Aboriginal Australians.
