b) The reactive control (R) should exhibit strong agglutination (black clumps against the white background). The minimally reactive control (Rm) should show slight but definite clumping. The non-reactive control (N) should not exhibit any agglutination and appear to have a uniform light-gray co...
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...

A nonreactive RPR card test with clinical evidence of syphilis can be seen in early primary syphilis; in secondary syphilis, as a result of the prozone reaction; and in some cases of late syphilis. The RPR card test cannot be used to test spinal fluids. The RPR card test may be reactive...

Negative Result (Non-Reactive):No Clumping or slight roughness. Note:A negative RPR Test result does not mean the patient is free of syphilis, particularly if the exposure was recent. It can take up to several weeks for antibodies to reach detection levels in the blood. As a result, repeat...
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...

pallidum in both tests, although one sample was reactive only at the 1:2 dilution in the RPR and its TPHA titer was 1:640. Six samples were only reactive for the TPHA test, while four were non reactive in both tests. The FTA-ABS was performed in these four samples and it was non ...
(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 ...
