Detection of Chlamydia trachomatis antigen by enzyme immunoassay in patients with pelvic inflammatory disease

Abstract

In 27 out of the 60 women clinically suspected to have pelvic inflammatory disease (PID) studied, the C. trachomatis antigen titre was found to be higher than the cut-off value. Since the presence of C. trachomatis antigen was detected in 45 per cent of women, it is suggested that all the PID patients may be investigated by ELISA to confirm the role of C. trachomatis as the etiological agent.
