How is chlamydia diagnosed?

Testing is the only way to know whether you have chlamydia. The U.S. Centers for Disease Control and Prevention (CDC) recommends annual screening for all sexually active females 25 years of age and younger and for older females with risk factors (such as those who have a new sex partner and those with multiple sex partners). All females with signs of infection of the cervix and all pregnant females should be tested.

The most sensitive chlamydia tests, called nucleic acid amplification tests (NAATs), can be performed on a urine specimen or a self-collected vaginal swab. An invasive genital exam is not always required. However, a chlamydia test can also be performed on a swab of the cervix collected as part of a pelvic exam or a urethral swab collected on males. It may take several days before you can get a test result.
