Signs and tests
The diagnosis of chlamydia infection involves sampling of the urethral discharge in males or cervical secretions in females. If an individual engages in anal sexual contact, samples from the rectum may also be needed. The sample is sent for a fluorescent or monoclonal antibody test, DNA probe test, or cell culture. Some of these tests may also be performed on urine samples.
The usual treatment for chlamydia is antibiotics, including tetracyclines, azithromycin, or erythromycin.
Early antibiotic treatment is extremely successful and may prevent the development of long-term complications. Untreated infection, however, may lead to complications.
