A, B and O antigens – In an individual, the blood cells may have A, B, or O antigens. Based on these, there are four primary blood types – A, B, AB and O. For type A blood, the blood cells will have A antigen. Similarly, there’s B antigens for B blood and A and B antigens for AB blood group. O blood type does not have any A or B antigen.

Immune reaction – If you have A blood type and you receive B blood, your immune system will treat B antigens as foreign bodies and attack them. Similarly, B blood individuals will react in the same manner if they receive A blood.

In case of individuals with AB blood type, they can receive blood from any individual. Individuals with AB blood group are referred to as universal recipient. But in case of donating blood, AB group can donate only to other AB individuals.

In case of people with O blood type, they can donate to everyone. They are referred to as universal doners. However, they can receive blood only from people with O blood type.
