Seridiagnosis of Syphilis
Abstract
-
The most frequently used serodiagnostic test for syphilis in Korea is VDRL test, which is one of several flocculation tests utilizing cardiolipin-lecithin as antigen. This test remains popular because it is easily performed, inexpensive, is standard for screening purposes, and is useful for following the serologic response to treatment. A common problem is weakly reactive (or 'rough' result) VDRL test or reactive VDRL in the absence of definite evidence of present or past syphilis; the diagnosis of syphilis in these cases should be confirmed by using the specific treponemal antigen tests. The Fluorescent Treponemal Antibody-Absorption (FTA-ARS) test is the result of continued attempts to improve the original FTA procedures. This test uses virulent T. pallidum (Nichols strain) as antigen and uses fluorescein-tagged antihuman globulin as reaction indicator. The FTA-ABS test is very sensitive in all stage of syphilis, especially in early syphilis. The FTA-ABS test was carried out on 448 persons with reactive and weakly reactive VDRL tests and divided the groups of routine physical check and out patients. (countinued..)
