If antigens on the surface of RBCs correspond to antibodies in the serum, agglutination of RBCs occurs. Therefore, the test result of blood typing can be determined by observing the agglutination of RBCs.

WebImmune-mediated RBC agglutination has two basic stages, the non-visible sensitization stage, consisting of the binding of antibodies to antigen determinants on the RBC membrane and the visible agglutination stage, resulting from random collisions between antibody-coated and sensitized cells, thus promoting agglutination (Figure 1).

WebWhat causes agglutination? Agglutination is caused by the formation of antibody-antigen complexes and occurs at room temperatures. Auto-agglutination is produced as a result of a complex formed between the patient's own RBC antigens and antibodies, mediated by cold-reacting antibodies. in car cd player with usbWebJun 24, 2024 · Agglutination of red blood cells. The agglutination of red blood cells (RBCs) is specifically called hemagglutination.. What causes the agglutination of RBCs can be attributed to hemagglutinins (a group of agglutinins).
