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.

ag·glu·ti·na·tion test

any of a variety of tests dependent on the clumping of cells, microorganisms, or particles when mixed with specific antiserum.
