When a person produces antibodies against their own red blood cells, as in cold agglutinin disease and other autoimmune conditions, the cells may agglutinate spontaneously. [1] This is called autoagglutination and it can interfere with laboratory tests such as blood typing and the complete blood count. [2] [3]
This leads to a markedly decreased red blood cell count and hematocrit and markedly elevated mean cell volume and mean cell hemoglobin concentration. [5]: 32–3 Red cell agglutination also interferes with routine methods for blood typing and blood compatibility testing, which rely on agglutination reactions. People with red cell agglutination ...
The anti-human globulin could bind to antibodies already attached to red blood cells and cause them to agglutinate. The invention of the antiglobulin test led to the discovery of many more blood group antigens. By the early 1950s, companies had begun producing commercial antisera for special antigen testing. [30]: 62–72
If agglutination does not occur with either antibodies that bind to type A or type B antigens, then neither antigen is present on the blood cells, which means the blood is type O. [1] [2] In blood grouping, the patient's serum is tested against RBCs of known blood groups and also the patient's RBCs are tested against known serum types.
People who have blood type A are more likely to suffer a stroke before the age of 60 than those with the most common blood type O, a new study reports.
An antiserum specific for HLA-A3 will then agglutinate HLA-A3 bearing red blood cells if the concentration of IgM in the antiserum is sufficiently high. Alternatively, a second antibody to the invariable (F c ) region of the IgG can be used to cross-link antibodies on different cells, causing agglutination.
