An evaluation of the IFA-GC procedure in a low risk population.

An automated indirect fluorescent antibody (IFA) test for gonococcal antibody was evaluated in 600 low risk females; 392 were prenatal patients from public and private clinics and 208 were apparently healthy females state employees in a multiphasic screening program. Clinical histories, physical examinations, and cervical cultures were obtained on all patients. The results of the cultures and serologic test were compared. Although the number of culture positive patients in the study was low, the lack of sensitivity of the IFA test in detecting gonococcal infection in these patients was disturbing. This observation and the number of apparent false positive IFA tests lead us to conclude that the automated IFA test for detection of gonorrhea shows promise, but we could not consider adopting the test in its present stage of development.
