Agglutination

Agglutination (from the Latin  agglutinare  - joining) is the aggregation of various particles, such as blood cells, bacteria, etc. It is an immunological reaction in which a connection between Antibody and antigen on the cell surface is made. Because antibodies have multiple binding sites, cells aggregate on the surface of which antigens are located.

Coagulation and agglutination have little in common ...

However, we often hear that when typing blood, the sample "clots". However, this is a false statement. So:
 *  Coagulation  = "blood-clotting"
 * is a chain of proteolytic reactions of plasma coagulation factors. The result is the polymerization of fibrin and the formation of a precipitate.


 *  Agglutination  = blood cell aggregation
 * is a reaction of type antigen - antibody. Non-covalent reaction, between plasma proteins and erythrocytes.
