What would happen if a recipient with blood type B receive blood from a donor with blood type O?

When you have a transfusion, it’s better to receive blood of the same ABO and RhD blood group. However, in an emergency or special circumstance, if the same blood group isn’t available, you might be given another group so your immune system won’t react. 

Know your blood group essentials

What would happen if a recipient with blood type B receive blood from a donor with blood type O?

Antigens are proteins or carbohydrates that our immune system can recognise.

Any antigen that’s ‘foreign’ to our immune system is destroyed by an antibody.

What would happen if a recipient with blood type B receive blood from a donor with blood type O?

Antibodies are attack molecules our immune system makes to protect us against foreign things such as bacteria and viruses. Antibodies can also form in response to different blood groups. Everyone is born with some antibodies and develops others over their lifetime.

What would happen if a recipient with blood type B receive blood from a donor with blood type O?

ABO is the major blood group system and is genetically determined. Your ABO type depends on whether you have A or B antigens on your red cells.

If you have the A antigen, you have group A red cells.

It’s possible to have both A and B antigens, which means the blood group is AB.

If you have blood type O, your cells don’t have either type of antigen.

The Rh blood group system has around 50 different red blood cell antigens. D is the most important antigen of the Rh system and it’s also known as RhD.

In Australia, about 83% of people have the D antigen on their red cells, so their blood type is called RhD positive. The other 17% don’t have the D on their red cells and are called Rh negative.

The percentage of Rh negative people varies in different countries. For example, less than 5% of India’s population are Rh negative.

Some people who are RhD negative will have an immune response to RhD and make antibodies. These antibodies can destroy any red cells which are RhD positive. This may occur with a transfusion or when pregnant with an RhD positive baby. Knowing your RhD group is also very important for women who are or may become pregnant as the antibodies can cause problems for the mum and baby. 

Because of the reasons above, it’s best that patients receive red cell components of identical ABO group and RhD type in their transfusions.

Sometimes that’s not possible, like in an emergency when the patient’s blood type is unknown and they need blood urgently.

In this instance, O Rh negative is the universal red cell donor blood and can be given to anyone with any blood type.

Safe blood types for each patient blood group:

Patients blood group

O- O-
O+ O-, O+
B- B-, O-
B+ B+, B-, O+, O-
A- A-, O-
A+ A+, A-, O+, O-
AB- AB-, A-, B-, O-
AB+ AB+, AB-, A+, A-, B+, B-, O+, O-

Plasma may contain anti-A, anti-B or both anti-A and anti-B antibodies depending on your blood group. If you require plasma you should only receive plasma that doesn’t contain an antibody which could attack the antigens on your own red cells.

Group A patients have A antigen on their red cells, so they can’t receive group O or group B plasma as the anti-A will attack their red cells. Group B patients have B antigen on their red cells, so they can’t receive group O or group A plasma as the anti-B will attack their red cells.

Group AB recipients can only receive group AB plasma. Group O recipients don’t have either A or B antigen, so can safely receive plasma of any blood group type.

Patient group Compatible plasma donor
A A, AB
B B, AB
AB AB
O O, AB, A, B

ABO identical platelets are usually preferred. However, in some circumstances, the need for other special requirements may be more important than providing the same ABO group.

Your healthcare team will work this out and you can always talk to them if you’d like more information. 

What would happen if someone with type B blood receive type A blood?

A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them.

What happens if you get transfused with the wrong blood type?

Transfusion The wrong blood type will cause reactions related to most endothelium, the red blood cells of the transfused blood will be destroyed by the recipient's antibodies right in the blood vessel and at the same time can reactions occur simultaneously, causing shock and causing the patient to die quickly.

What happens if you receive blood from an incompatible donor?

If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor's blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood.

Could a person with type A+ blood receive blood from a Type B donor?

In living donation, the following blood types are compatible: Donors with blood type A... can donate to recipients with blood types A and AB. Donors with blood type B... can donate to recipients with blood types B and AB. Donors with blood type AB... can donate to recipients with blood type AB only.
