Abstract
In 228 problem sera, the results obtained by fluorescent treponemal antibody test using Reiter and Nichols strain of Treponema pallidum were compal ed and a high degree of correlation existed between the results obtained by both methods RFTA test was as quite specific for syphilis as FTA test.
It is evident that the complement method of fluorescent treponemal antibody test for syphilitic sera with anticomplementary action gave negative results and thus this method should not be used as a routine technique of FTA or RFTA.
The author devised a quantitative technique of RFTA test by using the 2-fold dilutions of syphilitic sera. It was shown that the RFTA titers of the same spcimens were always higher than the RPCF or reagin titers and furthermor the RFTA titers did not correspond to the FTA titers. Possible explanations for this result are discussed.
