Abstract

On a total 233 sera from the VDRL reactive patients without a history of syphilitic symptoms or treatment for syphilis, TPHA and 19S(IgM)-FTA tests were performed, Also the reactivities of the 19 S (IgM)-FTA test in relation to the VDRL and the TPHA titers were observed. The results are summarized as follows: 1. Among 233 sera, 103 sera(44%) showed negative results in the 19S(IgM)- FTA test. 2. Reactivities of the 19 S(IgM)-FTA test were significantly increased in relation to the VDRL, titers arnong 233 sera reactive in the VDRL test: 47% in the VDRL titer 1: 1, 61% in 1: 2, 71% in 1: 4, 62% in 1: 8, 96% 1: 16 or more. 3. There was no relationship statistically (IgM)-FTA test and the TPHA titers. It can be derived from the above results that when a person with no history of treatment for syphilis and clear of any signs of syphilis shows a positive reaction in the VDRL test, he is less likey to be a syphilis patient when the VDRL titer is low.
