fluorescent treponemal antibody absorption test
FTA-ABS test; a highly specific treponemal antigen serologic test for syphilis; patient serum is absorbed with other treponemes to remove nonspecific antibodies, then reacted with a strain of Treponema pallidum fixed to a glass slide; specific antibodies adhering to the treponemes are demonstrated with fluorescein-labeled antihuman globulin.
