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.
