Examples of agglutination in the following topics:

  • Agglutination Reactions

    • Agglutination is the visible expression of the aggregation of antigens and antibodies.
    • Agglutination reactions apply to particulate test antigens that have been conjugated to a carrier.
    • Various methods of agglutination are used in diagnostic immunology and these incude latex agglutination, flocculation tests, direct bacterial agglutination, and hemagglutination.
    • Direct bacterial agglutination uses whole pathogens as a source of antigen.
    • Describe how agglutination reactions can be used to assess the presence of antibodies in a specimen
  • Precipitation Reactions

    • Precipitation reactions differ from agglutination reactions in the size and solubility of the antigen and sensitivity.
    • Precipitation reactions are less sensitive than agglutination reactions but remain gold standard serological techniques.
  • Cultivation of Specimen

    • Serum can be directly used in agglutination, precipitation, complement fixation, fluorescent microscopy, and enzyme-linked assays.
