that could be caused by syphilis. It can cause a wide range of symptoms, so doctors may recommend testing for syphilis even when symptoms aren’t severe or specific to this condition. Generally, diagnosing syphilis requires two tests: an initial screening test and a second confirmatory test. ...
If your RPR results come back positive, a confirmatory fluorescent treponemal antibody absorption (FTA-ABS) may be performed, depending on which lab you visit. This additional step to confirm a reactive RPR diagnosis helps to eliminate the chances of a false-positive result. OurT. Pallidum test...

(VDRL); either test may yield inaccurate results. Both tests become reactive about 1 to 2 weeks after initial infection. If either test result is positive, a confirmatory test is done: (1) by identifying the responsible bacterium,T. pallidumon dark-field examination of material from a genital...

We can see a reactive RPR, sometimes even as high at 1:256, due to other inflammatory processes that have nothing to do with syphilis, as their confirmatory test (whichever ones are used) is nonreactive. The TPPA “titer” is only a measure of the strength of the body’s reaction to ...
[22]The CDC recommends traditional testing, but if reverse screening is used all sera that produce reactive EIA/CIA results should be reflexively tested with a quantitative nontreponemal test. Sera with discordant results should be reflexively tested with a confirmatory TPPA test. If the result is...
The brand of screening (EIA 1) and confirmatory (EIA 2) tests differed by regional laboratory—Supplementary Table S3. Specimens that were non-reactive on first EIA were classified as HIV seronegative. All samples that were reactive using EIA 1 were re-tested using a second and different EIA...
Traditionally, screening involved an initial “nontreponemal” antibody test (ie, Venereal Disease Research Laboratory test or rapid plasma reagin [RPR] test) to detect biomarkers released from damage caused by syphilis infection, followed by a confirmatory “treponemal” antibody detection test (ie, ...
