capable of agglutination.
Capable of being agglutinated.
agglutination(ă-gloot″ĭn-ā′shŏn) [L. agglutinare, to glue to]
1. A type of antigen-antibody reaction in which a solid cell or particle coated with antigens drops out of solution when it is exposed to a previously soluble antibody. The particles involved commonly include red blood cells, bacteria, and inert carriers such as latex. Agglutination also refers to laboratory tests used to detect specific antigens or antibodies in disease states. When agglutination involves red blood cells, it is called hemagglutination. agglutinable (ĭn-ă-bĕl), adjective
2. Adhesion of surfaces of a wound.
The formation of an insoluble network of antigens and their antibodies, when the antigen is mixed with specific antiserum. Direct agglutination reactions are used, for example, in typing blood or in assessing the presence of antibodies against microorganisms.
A test for the presence of a specific antibody in which inert particles or cells with no foreign antigenic markers are coated with a known soluble antigen and mixed with serum. If clumping occurs, the patient's blood contains antibodies specific to the antigen. In the past, red blood cells were used as the carriers after they were washed to remove any known antibodies; currently, latex, bentonite, and charcoal also are used.
Clumping of platelets in response to immunological reactions.
Adhesion of the vaginal labia to each other, e.g., after inflammatory ulceration of the skin.
