RPR test:Rapid plasma reagin, a blood test forsyphilisthat looks for an antibody that is present in the bloodstream when a patient has syphilis. A negative (nonreactive) RPR is compatible with a person not having syphilis, but in the early stages of the disease, the RPR often gives false...
(non-reactive). A negative result means that there were no detectable traces of syphilis in your system. A positive result may indicate that you have syphilis. However, a positive diagnosis cannot be established until a TPA confirmation test can be run that differentiates syphilis from other ...
Weakly reactive, or Bordeline Whenever a screening test (RPR, VDRL) is positive, a more specific test (FTA-ABS, TP-MHA) should be used to confirm the test and rule out a "biologic false positive." A negative or "nonreactive" test may indicate: The patient doesn't have syphilis The ...
C. Reactive specimens are confirmed by Quantitative RPR Test and are sent to the Michigan State Laboratory for confirmation. VI. Quality Control: A. Reactive and non-reactive, minimally reactive and reactive control is tested with each batch of patient specimens. ...
Limitations of RPR Test Without some other evidence for the diagnosis of syphilis, a reactive non-treponemal test such as RPR does not confirmpalliduminfection. Any reactive RPR test must be confirmed with a specific or treponemal test such as TPHA, FTA-ABS test. ...
An RPR test result can be eitherreactiveornonreactive,depending on if antibodies were detected. AnonreactiveRPR result means there were no antibodies to syphilis found in the blood sample. If you have been confirmed as nonreactive and you or your doctor still believe that you are at high risk...
Congenital syphilis may be lurking Patients suspected of having syphilis should be screened with nontreponemal tests, such as the Venereal Disease Research Laboratory (VDRL) test or the RPR test, which become positive within 3 weeks of developing primary syphilis. Recalcitrant genital papules: this pa...
We report the case of an HIV-infected man with Kaposi sarcoma and secondary syphilis whose VDRL test and fluorescent treponemal antibody-absorbed test were repeatedly nonreactive. Correct diagnosis required biopsy of a skin lesion with ... CB Hicks - 《Annals of Internal Medicine》 被引量: 1410...

There are two different types of serologic assays for syphilis; nontreponemal and treponemal. A nontreponemal assay (traditional algorithm), such as the rapid plasma reagin (RPR) test, is an indicator of an active or recent syphilis infection and can be used to monitor response to therapy over...
