agglutination

 [ah-gloo″tĭ-na´shun]
1. the action of an agglutinant substance.
2. the clumping together in suspension of antigen-bearing cells, microorganisms, or particles in the presence of specific antibodies (agglutinins).
Agglutination reactions. From Applegate, 2000.
3. the process of union of the surfaces of a wound. adj., adj agglutina´tive.
cross agglutination the agglutination of particulate antigen by an antibody raised against a different but related antigen; see also group agglutination.
group agglutination agglutination, usually to a lower titer, of various members of a group of biologically related organisms by an agglutinin specific for one of that group. For instance, the specific agglutinin of typhoid bacilli may agglutinate other members of the colon-typhoid group, such as Escherichia coli and Salmonella enteritidis.
intravascular agglutination clumping of particulate elements within the blood vessels; used conventionally to denote red blood cell agglutination.
platelet agglutination the clumping together of platelets owing to the action of platelet agglutinins; such agglutinins are important in platelet typing.
agglutination test any test based on an agglutination reaction, as serologic tests for specific antibodies.
