Choice of tests and interpretation of test results depend on various factors, including previous syphilis, possible exposure to syphilis, and results of testing. If patients have had syphilis, a reaginic test is done. A 4-fold increase in titer suggests new infection or failed treatment. If pat...

Because of the false-positive test results with initial treponemal testing (ie, CIA or EIA) and a negative RPR and TPPA result in low-risk patients or low-prevalence populations, clinician education on the reverse sequencing algorithm and interpretation and limitations of syphilis serologic test ...
Despite the above guidance, syphilis interpretation is challenging, and there areno hard or fast rulesother than the initial screening test – the EIA often remains positive throughout life despite treatment. The patient must know this in case they are tested elsewhere. Tointerpret serology, you ...
Interpretation of reactive tests Screening using an initial automated treponemal test (EIA or CLIA) is done by many laboratories, especially those with high sample volume. A negative treponemal test likely indicates the absence of syphilis and generally no further testing is required. However, recent...
Result Interpretation of Rapid Plasma Reagin (RPR) Test Positive Result (Reactive):Clumping (Characteristic clumping ranging from marked and intense (reactive) to Reactive (R) slight but definite (minimally to moderately) reactive). Negative Result (Non-Reactive):No Clumping or slight roughness. ...
As a result of our search, we proved that different clinical situations (cancer, lupus erythematosus) were accompanied by false-positive tests for syphilis, but we did not find any mention of false-positive test in atopic dermatitis (AD). Meanwhile, the disease is not rare in different countri...
The CDC recommends that any woman who has had a fetal demise beyond 20 weeks of gestation receive a serological test for syphilis. They also recommend that no new mother or infant should be permitted to leave the hospital without at least 1 documented serological test result for syphilis recorde...
