Question: what does the agglutination mean?
Answer: Published on Nov 27, 2019. Agglutination is the clumping of the red blood cells due to the antigen-antibody reaction. Agglutination occurs when agglutinogen combines with its corresponding agglutinin. Agglutinogens are the antigens that cause agglutination, and the corresponding antibodies are called agglutinins.
