66Agglutination reaction
- If red blood cells from one blood type are mixed
with antibodies from the plasma of the other
blood type, an agglutination reaction occurs. In
this reaction, RBC stick together because of
antigen-antibody binding.

72Blood typing
- Agglutination (clumping) of red blood cells
occurs when with A-type antigens are mixed with
anti-A antibodies and when cells with B-type
antigens are mixed with anti-B antibodies. No
agglutination would occur with type O blood (not
shown).
