Testing for chlamydia is relatively simple and is usually performed through a urine test or culture swab.
The culture tests used to diagnose chlamydia infection involve a sampling of the urethral discharge in males or cervical secretions in females. For women, a health care provider may take a culture swab of the discharge in the cervix. For men, a health care provider may insert a slim swab into the end of the penis to get a sample from the urethra. In some cases, a swab of the anus may also need to be tested for the presence of chlamydia.
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, which can also indicate the presence of chylamydia infection.
