The antigens and antibodies combine by a process called agglutination. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins. In the blood, the antigens are specifically and with high affinity bound by antibodies to form an antigen-antibody complex.
This image explains agglutination in the blood. Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare (glueing to).. Agglutination is a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps usually as a response to a specific antibody.
Agglutinogen is an antigen [1] that causes the formation of agglutinins in the body and leads to agglutination, such as hemagglutination, which involves red blood cells (RBCs). The kind of agglutinogens present on the red blood cells helps determine the blood type of a person.

A schematic diagram of the experimental setup to detect hemagglutination for blood typing. Hemagglutination blood typing detection: [24] This method consists of measuring the blood’s reflectance spectrum alone (non-agglutination), and that of blood mixed with antibody reagents (agglutination) using a waveguide-mode sensor. As a result, some ...
In an agglutination test, a person's serum (which contains antibodies) is added to a test tube, which contains a particular antigen. If the antibodies interact with the antigen to form immune complexes , called agglutination, then the test is interpreted as positive.
Hemagglutination, or haemagglutination, is a specific form of agglutination that involves red blood cells (RBCs). It has two common uses in the laboratory: blood typing and the quantification of virus dilutions in a haemagglutination assay .
1) Antibodies (A) and pathogens (B) circular in the blood. 2) The antibodies bind to pathogens with complementary antigen sequences, engaging in opsonization (2a), neutralisation (2b), and agglutination (2c). 3) A phagocyte (C) approaches the pathogen, and Fc region (D) of the antibody binds to one of the Fc receptors (E) on the phagocyte.
