WebMany laboratories in North America now perform syphilis testing using the reverse sequence testing algorithm. This algorithm begins with a screening treponemal test (TT). TTs detect IgG and IgM antibodies specic to T. pallidum. A positive test indicates that an individual has been infected with syphilis. WebReverse Syphilis Screening algorithm: This algorithm starts with a treponemal antibody assay and if positive, reflexes to the syphilis RPR with titer. Specimens that are positive for treponemal antibodies but negative on RPR will reflex to a second treponemal antibody assay to confirm results. Labcorp aligns with the CDC and offers: Treponema ...

WebAn alternative approach is to use a reverse sequence algorithm, which uses a TT to screen and a quantitative NTT to confirm the positives. A second confirmatory TT may be done in some laboratories. TTs such as the treponemal-specific enzyme immunoassay (EIA) are more sensitive tests for syphilis.
