pertaining to or characterized by fluorescence.
fluorescent antibody test a test for the distribution of cells expressing a specific protein by binding antibody specific for the protein and detecting complexes by fluorescent labeling of the antibody. Called also FAB test.
fluorescent treponemal antibody absorption test the standard treponemal antigen test for syphilis: Nonspecific antibodies are removed from patient serum, which is then reacted with Treponema pallidum fixed to a glass slide. Specific antibodies adhering to the treponemes are demonstrated with fluorescein-labeled antihuman globulin. Positive tests are seen in about 85 per cent of cases of primary syphilis, 100 per cent in secondary syphilis, and 98 per cent in late syphilis. The test remains positive for life even after syphilis has been successfully treated. Called also FTA-ABS test.

fluorescent antibody test

A laboratory test for the identification of a wide range of infective and other agents for which specific antibodies, linked to fluorescein, are held. The observation of fluorescence demonstrates that the antibody has attached to the corresponding substance (ANTIGEN), which must therefore be present.

Fluorescent antibody test (FA test)

A test in which a fluorescent dye is linked to an antibody for diagnostic purposes.
