Syphilis reverse testing algorithm
WebSyphilis has plagued society since the late 15th century, although its causative agent, the spirochete T pallidum, was not recognized until 1905.1,2 T pallidum This highly infectious STI poses severe consequences to women and babies when infection occurs during pregnancy, with infection rates higher among women who lack prenatal care. 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.
