Abstract

Treponemal (fluorescent treponemal antibody-absorption [FTA-ABS]) and nontreponemal (Venereal Disease Research Laboratory [VDRL] and automated reagin) tests were performed on patients consecutively admitted to a general hospital. The FTA-ABS test was reactive in 16.8% of the patients compared with a 9.5% reactivity rate for the VDRL test. A history of treated or untreated syphilis was obtained in 73 of 78 patients with a reactive FTA-ABS test; in the 5 remaining patients, the diagnosis of syphilis could not definitely be established. An additional 40 (8.6%) patients demonstrated borderline reactivity in the FTA-ABS test. Of these, eight were found to have had syphilis. In the present study, the FTA-ABS test was reactive more often than either the VDRL or the automated reagin tests; however, both the nontreponemal and treponemal tests were reactive in three patients who had previously undetected, untreated syphilis. The results of this study suggest that syphilis should be considered more
