[A specific stimulation test of the peripheral blood lymphocytes in the diagnosis of syphilis].

The authors analyze the results of laboratory studies on the diagnosis of syphilis with the use of this test. T. pallidum has been used as an antigen. The study has involved 234 patients with active and latent forms of syphilis, as well as donors and subjects with nonspecific positive serologic reactions. The test has yielded negative results in 27 (12%) patients; of these, in only 1 of the 170 patients with active syphilis.
