The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).
Nontreponemal tests are screening tests, very rapid and relatively simple, but need to be confirmed by treponemal tests. [1] Centers for Disease Control and Prevention (CDC)-approved standard tests include the VDRL test (a slide test), the rapid plasma reagin (RPR) test (a card test), the unheated serum reagin (USR) test, and the toluidine red ...
The Wassermann test or Wassermann reaction (WR) [1] is an antibody test for syphilis, named after the bacteriologist August Paul von Wassermann, based on complement fixation. It was the first blood test for syphilis and the first in the nontreponemal test (NTT) category. Newer NTTs, such as the RPR and VDRL tests, have mostly
Because seroconversion refers to detectability by standard techniques, seropositivity status depends on the sensitivity and specificity of the assay. As a result, assays, like any serum test, may give false positives or false negatives and should be confirmed if used for diagnosis or treatment. [5]
In the test, gelatin particles are sensitized with T. pallidum antigen. Patient serum is mixed with the reagent containing the sensitized gelatin particles. The particles aggregate to form clumps when the patient serum is positive for syphilis. In other words, the patient's serum contains antibodies to T. pallidum. A negative test shows no ...
