Tests detect biomarkers that are released during cellular damage that occurs from the syphilis spirochete. In contrast treponemal tests look for antibodies that are a direct result of the infection thus‚ anti-treponeme IgG‚ IgM and to a lesser degree IgA Non Treponemal Non-treponemal serologic tests for syphilis include VDRL (Venereal Disease Research Laboratory) test and RPR (Rapid Plasma Reagin) test. VDRL has been in use for several years now and the only difference between VDRL and RPR is that
