Laboratory assay overview
PrEP use only: This test is for baseline testing and monitoring for syphilis in patients administered HIV PrEP. This test aligns with the CDC-supported reverse serologic testing algorithm for syphilis using a combination of both treponemal and nontreponemal antibody tests. The reverse syphilis testing algorithm begins with a treponemal antibody assay. Positive samples reflex to RPR (nontreponemal). If the RPR is positive, RPR titer will be determined. If the RPR is negative, a second treponemal antibody assay will be performed to confirm the presence of treponemal antibodies. Interpretation of results obtained must take into account patient symptoms and clinical history.

Laboratory assay overview
This test detects antibodies to Treponema pallidum and can be used in conjunction with a nontreponemal assay to aid in the diagnosis of syphilis infection. This test is not recommended as a stand-alone test for general screening purposes for syphilis, nor should it be used to evaluate response to therapy. To screen for and diagnose syphilis infection, a reflex cascade that includes both RPR and a treponemal-specific assay should be utilized per current guidelines.
