The enzyme-amplified immunoassay IDEIA (CellTech Diagnostics), which measures lipopolysaccharide antigen, and Chlamydiazyme (Abbott Laboratories, North Chicago, Ill.), which measures several antigenic components of Chlamydia trachomatis, were compared for specimens from urethral swabs from 235 men attending a clinic for sexually transmitted diseases (culture prevalence of 14.9%) and 458 endocervical swabs from women attending planned parenthood and obstetrics-gynecology clinics (culture prevalences of 5.9 and 7.7%, respectively). Compared with cell culture, the percent sensitivites, specificities, and positive and negative predictive values for IDEIA were 62.5, 99.5, 95.2, and 94.3%, respectively, for specimens from men and 96.3, 97.9, 74.3, and 99.8%, respectively, for specimens from women; results for Chlamydiazyme for specimens from men were 81.8, 99.5, 96.4, and 97.1%, respectively, and for specimens from women, results were 85.2, 99.3, 88.5, and 99.1%, respectively. Although the specificities of IDEIA and Chlamydiazyme were comparable, the sensitivity of IDEIA appeared higher for women (96.3%) than for men (67.5%), while the sensitivities of Chlamydiazyme were similar for men (81.8%) and women (85.2%). Western blot (immunoblot) analysis of the detector reagents from the two immunoassays indicated that the differences in performance observed for the two immunoassays may be due to measurement of different antigens.
