WebNon-treponemal tests, also called screening tests (RPR and VDRL), do not detect antibodies specific for syphilis and are based upon the reactivity of serum from infected patients to a cardiolipin-cholesterol-lecithin antigen (regain). RPR and VDRL results should have a quantitative titer reported with them (1:2, 1:4, 1:8, etc.). WebThe RPR is not valid in a CSF evaluation because of a high false-positive rate. The CSF-VDRL is specific but not sensitive, so false-negative results can occur.

WebThe 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.
