is branch of immunology that traditionally deals with in vitro diagnostic testing of serum. The ability to detect even minute amounts of target antibodies or antigens, , is an important characteristic of such in vitro tests, as is , or the test’s ability to eliminate reactions with unrelated or distantly related antigens. tests, such as the use of a latex test for strep throat, are an example of accurate in vitro serological tests, which produce antibody-mediated cell clumping that can be visualized for positive identification of microbial infection. In contrast, reactions, such as serotyping for species identification, produce insoluble antibody-antigen complexes in vitro that can be visualized for positive identification of a microbial infection.

Monoclonal antibodies are used mainly for diagnostic testing (both lab and home kits), and for targeted therapeutic purposes. True False

In immunofluorescence testing, a fluorescent is attached to a specific antibody to provide a sensitive test for the presence of a specific antigen or antibody.
