[Evaluation of sensitivity and specificity of 3 reagents of direct immunofluorescence in the diagnosis of Chlamydia trachomatis].

The sensitivity, specificity, positive and negative predictive values and positive and negative false percentage of three monoclonal immunofluorescence reagents for direct diagnosis of Chlamydia trachomatis infections were evaluated, 150 cervical specimens and 50 samples of peritoneal liquid of patients with pelvic inflammatory disease, were studied. The results showed that the reagents against the main protein of external membrane of Chlamydia introduced high sensitivity but minor specificity than the reagent of immunofluorescence direct against then chlamydial lipopolysaccharide.
