Fourteen (17.5%) controls with HCV(-)/RPR(+) had a non-reactive TPHA test. These represented 1.1% of all HCV-positive and 0.3% of all HCV-negative subjects (P<0.001). A significantly increased prevalence shown by false-positive tests for syphilis was observed in elderly HCV-seropositive ...
Dunseth et al. underlined the necessity of differentiation between analytical false-positive results of lues tests from clinical false-positive results. A positive syphilis IgG screen with negative RPR and T. pallidum particle agglutination assay (TP-PA) confirmatory testing could be considered an analy...
Syphilis seropositivity was detected in overall 2.9‰ (N = 148) of the cases. RPR-negative cases, i.e. past infections were confirmed in 36% (53/148); weak-reactive RPR (titres≤8) cases, i. e. past/early acute infections in 37% (55/148); strong-reactive RPR (titres>8) cas...

The results indicate that when the FTA ABS test is performed by the standard technique using a commercially prepared sorbent it may occasionally be reactive in patients with genital herpes. It is conceivable that in these circumstances syphillis syphilis be incorrectly suspected or diagnosed, ...
RPR test.In this study BFPs were significantly more common in HCV positive patients compared to HCV-negative ones.Eosinophil abnormality can be considered as a predictor for BFP.Excessive BFPs must be considered in assessing the frequency of syphilis in a HCV-positive population and the importance...

pallidum DNA and/or RNA were negative.A lack of demonstrable T. pallidum DNA or RNA suggests that blood donors with confirmed-positive results in STS are unlikely to have circulating T. pallidum in their blood and that that their blood is unlikely to be infectious for syphilis....
New reverse sequence syphilis testing algorithms have detected significant numbers of serodiscordant patients with a confirmed positive treponemal tests and negative non- treponemal tests. The risks of sequelae in these patients in the antibiotic era are unknown. Our goal was to determine the ...
CONCLUSION: Approximately half of donors with FTA-ABS-positive test results reported a syphilis history. There was no difference between reported BFP conditions for FTA-ABS-positive or FTA-ABS-negative cases and controls. This information may be useful when providing donors with better predonation ...
