| erythrocyte transfusion | The transfer of erythrocytes from a donor to a recipient or reinfusion to the donor. (12 Dec 1998) |
|---|---|
| erythrocyte volume | Volume of circulating erythrocytes. It is usually measured by radioisotope dilution technique. (12 Dec 1998) |
| acid agglutination | The clumping together of certain microorganisms at high hydrogen ion concentration. (05 Mar 2000) |
| agglutination | <cell biology, haematology> The clumping together of cells due to the binding of agglutinin (a protein) molecules on the surface of each cell. The clumping together of two organisms of the same species for the purpose of sexual reproduction. Often conducted by means of acarbohydrate on one organism and a protein on theother, resulting in a glycoprotein. (06 May 1997) |
| agglutination test | <investigation> A serologic test to demonstrate the presence of antibodies in the blood. It is dependent on the clumping of cells, microorganisms, or particles when mixed with specific antiserum. See: agglutination. (04 Jul 1999) |
| bacteriogenic agglutination | The clumping of erythrocytes as a result of effects of bacteria or their products. (05 Mar 2000) |
| passive agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| group agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
| mixed agglutination | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |
| mixed agglutination reaction | Immune agglutination in which the aggregates contain cells of two different kinds but with common antigenic determinants; when used to identify isoantigens, the test cells are exposed to appropriate isoantibody, washed, and then mixed with indicator erythrocytes that combine with free sites on the test cell-attached isoantibody. Synonym: mixed agglutination. (05 Mar 2000) |
| cold agglutination | The agglutination of red blood cells by their own serum (see autoagglutination), or by any other serum when the blood is cooled below body temperature, but most pronounced below 25캜; the phenomenon results from cold agglutinins; may be seen occasionally in the blood of apparently normal persons or as a pathologic finding in patients with primary atypical pneumonia, infectious mononucleosis, and other viral diseases, certain protozoan infections, or lymphoproliferative neoplasms. See: autoagglutination. (05 Mar 2000) |
| cold agglutination test | <investigation> A test for blood antibodies which are present in certain peculiar types of pneumonia (atypical pneumonia, Mycoplasma) (27 Sep 1997) |
| cross agglutination | Agglutination by antibodies specific for minor (group) antigens common to several microorganisms, each of which possesses its own major specific antigen. Synonym: cross agglutination. (05 Mar 2000) |
| sperm agglutination | Agglutination of spermatozoa. (05 Mar 2000) Previous: Spens, Thomas, spent, speract, sperling, sperm, spermaceti, spermacytic seminomaNext: sperm agglutination, spermalist, spermaphore, spermary, sperm-astersperm agglutination Agglutination of spermatozoa by antibodies or autoantibodies. (12 Dec 1998) |
| spontaneous agglutination | The non-specific clumping of organisms in saline related to lack of polar groups in electrolyte solution. (05 Mar 2000) |
