[Development of a regional external quality assessment program of the diagnosis of syphilis in the Volga Federal District].

In 2004, the authors first developed and implemented a regional external quality assessment program (REQAP) for the diagnosis of syphilis in the Volga Federal District (VFD). Its objective is to improve the quality of studies in the clinical laboratories of AIDS prevention and control centers (AIDS PCC) using a cardiolipin antigen precipitation microtest and/or enzyme immunoassay (EIA) for the diagnosis of syphilis and to compare the reproducibility of results at the laboratories. The program includes a theoretical stage--the issues concerning different aspects of the diagnosis of syphilis and the variants of replies to them; a practical stage--to solve enciphered problems, to draw up protocols; and a final stage--to sum up the results of two former stages and to organize a seminar.
