Chlamydia trachomatis is associated with infections of the mucous membranes of the urogenital system, the upper respiratory tract, and the eye. The usefulness of serological tests depends on the site of infection, duration of disease, infection serovars and previous exposure to chlamydia antigens. Because C. trachomatis is ubiquitous, there is a high prevelance of antibodies in sexually active populations. Individuals may be reinfected and IgM antibodies may not appear. IgG antibodies may persist even after treatment, making assessment of a single IgG titer difficult. Consequently, serological diagnosis is seldom used to diagnose genital tract infections. Instead, nucleic acid amplification testing (NAAT) or culture should be considered to detect Chlamydia trachomatis. Culture can also be used to diagnose infact respiratory infection or conjunctivitis.
