(2,3) Traditionally, the immunologic syphilis screening algorithm begins with a nontreponemal immunoassay (eg, rapid plasma reagin [RPR]), and if this result is positive, then the specimen is reflexed to an immunoassay for Treponema specific (treponemal) antibodies, which can serve as confirmation for the positive screen (Figure, A).
