autoagglutination

 [aw″to-ah-gloo″tĭ-na´shun]
1. clumping or agglutination of an individual's cells by his own serum (containing autoantibody), as in autohemagglutination. Autoagglutination occurring at low temperatures is called cold agglutination.
2. nonspecific clumping or agglutination of particulate antigens that does not involve antibody.

au·to·ag·glu·ti·na·tion

(aw'to-ă-glū'ti-nā'shŭn),
1. Nonspecific agglutination or clumping together of cells (for example, bacteria, erythrocytes) caused by physical or chemical factors.
2. The agglutination of erythrocytes by a specific autoantibody present in one's own serum.

Autoagglutination

autoagglutination

The aggregation of red blood cells in a person’s own serum, often caused by a cold-reacting antibody, as seen in cold agglutinin disease or other autoimmune haemolytic anaemias.

(aw'to-ă-glū'ti-nā'shŭn)
1. Nonspecific agglutination or clumping together of cells (e.g., bacteria, erythrocytes) due to physical-chemical factors.
2. The agglutination of red blood cells by specific autoantibody present in one's own serum.

autoagglutination

The spontaneous clumping together of red blood cells. This is a feature of the AUTOIMMUNE DISEASE haemolytic anaemia

autoagglutination

agglutination of red blood cells due to generation of a specific autoantibody

autoagglutination

1. clumping or agglutination of an individual's cells by its own serum, usually because of the presence of autoantibodies, as in autohemagglutination. Autoagglutination occurring at low temperatures is called cold agglutination.
2. agglutination of particulate antigens, e.g. bacteria, in the absence of specific antibodies.

influenzae in most laboratories, although this technique is prone to misinterpretation because of nonspecific agglutination, cross-reactions, or autoagglutination.
Because of these regional factors, the precise cutoffs and rules that proved most efficient in our laboratory may not be the optimal rules to apply in laboratories working in other regions of the globe, (3) Samples were collected consecutively in a period of 2 months, so some uncommon positive findings were not observed during the study, such as malaria, RBC autoagglutination, and rouleaux formation.
Procedure note: Because of nonspecific autoagglutination, appropriate positive and negative controls are always included in the 0157 and H7 assays.
If the specimens have inadvertently cooled, warming to 37 C for at least 10 minutes will cause the cold antibody to elute back from the cells into the serum and the autoagglutination will disperse completely in most cases.
