Question

What are the expected clumping results when each type of blood is mixed with each antibody? The antibodies are Anti-A, Anti-B, and Anti-Rh. How do I know if the different blood types (A+, A-, B+, B-, etc) clump with any of the antibodies?

Answer 1

Agglutination (clumping) will occur when blood that contains the particular antigen is mixed with the particular antibody.

Explanation:

Agglutination of blood types takes place as follows:

1. A+ - Agglutination with Anti-A and Anti-Rh. No agglutination with Anti-B.
2. A- - Agglutination with Anti-A. No agglutination with Anti-B and Anti-Rh.
3. B+ - Agglutination with Anti-B and Anti-Rh. No agglutination with Anti-A.
4. B- - Agglutination with Anti-B. No agglutination with Anti-B and Anti-Rh.
5. AB+ - Agglutination with Anti-A, Anti-B and Anti-Rh.
6. AB- - Agglutination with Anti-A and Anti-B. No agglutination with Anti-Rh.
7. O+ - Agglutination with Anti-Rh. No agglutination with Anti-A and Anti-B.
8. O- - No agglutination with Anti-A, Anti-B and Anti-Rh.
