The utility of antiglobulin testing in blood group serology

Focusing on the detection of antigen-antibody reactions, this seminar paper discusses methods for cell phenotyping and identifying blood group antigens, which can be either IgG or IgM. It highlights the structural characteristics of IgG, noting its monomeric form and the insufficient distance between Fab regions for direct agglutination. Consequently, the paper emphasizes the need for enhanced techniques to effectively detect IgG reactions in biological studies.
