Presently, the screening of syphilis is dependent mainly on serological tests. In the sexually transmitted disease clinic, syphilis serology is a basic screening test. The results VDRL test among of 150 HIV (82 males, 68 females) infected, regardless to immune status (CD4+ count), were studied. It was found that in 2 cases, the VDRL was biologically false reactive (VDRL positive, TPHA negative), who had CD4+ count >200 /mL, giving the incidence rate equal to 1.3 % (1.2 % for male and 1.5 % for female).
