Order RPR Test (Syphilis) | Rapid Plasma ReaginThe rapid plasma reagin (RPR) test is a blood test used to screen for syphilis, a bacterial infection caused by Treponema pallidum. It detects antibodies that the body produces in response to the infection, rather than the bacterium itself. Because those antibodies can take time to appear, the RPR test is typically interpreted alongside a person's history and any prior or follow-up testing.
About RPR Test (Syphilis) | Rapid Plasma Reagin in Madera
The RPR test is a screening tool, not a confirmatory one.
The RPR test works by mixing a blood sample with a reagent containing cardiolipin, a lipid antigen. If reagin antibodies are present, the sample clumps, producing a visible reaction. These antibodies are not specific to Treponema pallidum, so a reactive result can occur for reasons other than syphilis, including certain autoimmune conditions, other infections, and pregnancy.
Because of that limited specificity, a reactive RPR is usually followed by a treponemal test, such as a TP-PA or enzyme immunoassay, to confirm whether the antibodies are truly related to syphilis. Some testing strategies reverse this order, starting with a treponemal test and using RPR to assess disease activity.
RPR results are also reported as a titer, a ratio that reflects how much antibody is present. Titers can help gauge whether an infection is active and whether treatment is working. A falling titer generally suggests a response to therapy, while a rising or persistently high titer may prompt further evaluation. Results should always be discussed with a healthcare provider who can interpret them in context.
