People with type A blood have the antigen A on the surface of their RBCs, while people with type B blood have the B antigen. Individuals with type AB blood have both A and B antigens.
Explanation:
- An antigen is any substance that causes your immune system to produce antibodies against it.
- An antigen may be a substance from the environment, such as chemicals, bacteria, viruses, or pollen. An antigen may also form inside the body.
- When an antigen enters the body, it stimulates the immune system to produce antibodies.
- Antigens are any substance that stimulates the immune system to produce antibodies. Antigens can be bacteria, viruses, or fungi that cause infection and disease.
- Blood types are most important to know if you are needing a transfusion, but it appears that different blood types may have an impact on certain diseases.
- Rh+ indicates there are Rh antigens. Antibodies (in the blood plasma): B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
- There are more than 600 other known antigens, the presence or absence of which creates rare blood types. Your blood type is considered rare if you lack antigens that 99% of the people are positive for.
