If you have been confirmed as nonreactive and you or your doctor still believe that you are at high risk for syphilis, it is advised to wait three weeks and retest to confirm you did not receive a false-negative result. A reactive RPR test result is considered abnormal because antibodies ...
CDC prepared three panels that included: a qualitative panel comprised of 455 syphilis reactive/nonreactive specimens; a quantitative panel comprised of 50 syphilis reactive (titer 1:64 to 1:1024) specimens; and a reproducibility panel comprised of 15 nonreactive and reactive (titer 1:1 to 1:...

a) The RPR test becomes reactive around the chancre stage of syphilis or within 1 to 2 weeks after the chancre first appears. Titers peak during the secondary stage and then decline slowly. Approximately half of the untreated infections will continue to show some level of reactivity, sometimes...
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. ...

RPR test may be positive in low titre when treatment is started late. In late syphilis (cardiovascular, neurological or gummatous lensions) reagin titres may rise. In some cases of neurosyphilis, reagin test in serum may be non-reactive but positive with CSF. ...
RPR test, also known as therapid plasma regain test,is a modified version of the VDRL nontreponemal test. This test is a blood test used to screen for syphilis. This test is based on detecting the nonspecific antibodies for syphilis that the body produces while fighting the infection. This ...
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...
