Syphilis: RPR With Reflex to RPR Titer

Also known as: Nontreponemal, Rapid Plasma Reagin, RPR

Clinical Use

Order Test

Use

This test can be used to follow treatment response in patients being treated for syphilis infection. This assay should not be used to screen for syphilis infection. To screen for syphilis infection, a reflex cascade that includes both RPR and a treponema-specfic assay should be utilized, such as Treponema pallidum (Syphilis) Screening Cascade [082345] or Rapid Plasma Reagin (RPR) Test With Reflex to Quantitative RPR and Confirmatory Treponema pallidum Antibodies [012005]. See Related Information to view these tests.

Special Instructions

This assay should not be used to screen for syphilis infection. Instead, a reflex cascade that includes both RPR and a treponema-specific assay should be utilized, such as the Treponema pallidum (Syphilis) Screening Cascade or the Rapid Plasma Reagin (RPR) Test with reflex to quantitative RPR and confirmatory Treponema pallidum antibodies.

Limitations

This test is not intended for screening purposes and should not be used as a primary diagnostic test for syphilis infection. It is important to note that nontreponemal tests such as RPR can produce false-positive results due to other conditions and require confirmation with a treponemal test. Additionally, biological false nonreactive results can occur in patients with compromised immunocompetence or early in the course of infection before seroconversion.
