A correlative study of Papanicolaou smear, fluorescent antibody, and culture for the diagnosis of Chlamydia trachomatis.
A prospective study of 300 patients undergoing therapeutic termination of pregnancy was conducted. A Papanicolaou smear was obtained and a clinical evaluation of the cervix was made. Specimens from the cervix were examined by both direct fluorescent antibody and culture techniques for the presence of Chlamydia trachomatis. The presence of inflammation on Papanicolaou smear could be correlated with C trachomatis isolation. Papanicolaou smear findings consistent with C trachomatis lacked both sensitivity and specificity when compared with direct fluorescent antibody and/or culture techniques. A correlation was found between the clinical diagnosis of cervicitis and C trachomatis. This interrelationship was absent when the component findings of cervicitis (ectopy, friability, and purulent mucus) were examined independently.
