Microbiological aspects of the diagnosis of Chlamydia trachomatis.
The available diagnostic methods for Chlamydia trachomatis infection comprise serology (indirect detection) and culture, antigen detection and nucleic acid amplification (direct detection). The rationale, applications, advantages and disadvantages of the methods and diagnostic targets are discussed. Compared to conventional methods, nucleic acid amplification tests have increased sensitivity. This allows samples to be taken at home by the patient herself and mailed directly to the laboratory. Public health strategies implying home sampling for asymptomatic men and women result in a lower prevalence and a lower risk of short-term complications in terms of pelvic inflammatory disease (PID). The importance of predictive values and the association with prevalence are highlighted.
