Syphilis Test How we test for Syphilis Our clinicians use the Rapid Plasma Reagin (RPR)syphilis test, which looks for antibodies that fight a syphilis infection. If positive, a Treponemal Pallidum Assay (TPA) test is used to confirm the presence of the bacteria....
This review aims to assess immunochromatographic point-of-care treponemal tests for accuracy and compare these tests with the rapid plasma reagin (RPR) card.doi:10.1097/01.ogx.0000524475.36903.85Rogozinska, E.Kara-Newton, L.Zamora, J. R....
However, RPR and VDRL antigens are not treponemal specific, and whole TP extracts are not reproducible and contain a certain amount of contaminating materials such as flagella, which may lead to a nonspecific reaction in assays of test serum. Manufacturer Dewei Medical Equipment Co., Ltd...

for syphilis, each with their own method of detecting the presence of the disease. Some of the most common types include enzyme-linked immunosorbent assays (ELISAs), rapid plasma reagin (RPR) tests, and treponemal-specific tests such as the T. pallidum particle agglutination (TPPA) test. ...
linked immuno-sorbent assay (ELISA) could be caused by hemolysis. The RPR had low sensitivity in suspected syphilis neonates, and the colloidal gold test (SYP) was suitable for emergency treatment. The treponema pallidum particle agglutination test (TPPA) was fit for the diagnosis of syphilis [...
One study demonstrated that undiluted serum with high titers of nontreponemal antibodies can result in false-negative RPR testing results Treatment: No new studies examining harms of treatment in pregnant women were identified Included diagnostic accuracy studies only report on the test inaccuracy of ...
Latent syphilis (Latent Syphilis): Patients with positive serological test results for syphilis (RPR, VDRL) but without clinical symptoms of nervous system involvement and signs of active infection. 2. Neurosyphilis (With NS): Patients with confirmed neurosyphilis based on clinical symptoms such as...
A field trial carried out in Mozambique found that the diagnostic accuracy of the ICS compared favourably with the RPR and standards consisting of TPHA, RPR and direct immunofluorescence stain undertaken in a reference laboratory.55 However, for the time being, given the challenges in making a ...
Samples were also tested by the rapid plasma Reagin (RPR) test. With TPPA as reference assay, the sensitivity and specificity of EIA were 95.3% and 97.8%, and of the POCT were 59.6% and 99.4% respectively. The sensitivity of the POCT and EIA for active syphilis cases (TPPA positive and...
