FTA-ABS test

fluorescent

[floo͡-res´ent] 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" >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.

fluor·es·cent trep·o·ne·mal an·ti·bod·y-ab·sorp·tion test

a sensitive and specific serologic test for syphilis using a suspension of the Nichols strain of Treponema pallidum as antigen; the presence or absence of antibody in the patient's serum is indicated by an indirect fluorescent antibody technique. Synonym(s): FTA-ABS test

FTA-ABS test
