Diagnosis of Chlamydia

Most people do not have symptoms. They will be tested if they are at high risk.

In others, the doctor will ask about symptoms and health history. Questions will also be asked about sexual history. A physical exam will be done. Chlamydia may be suspected in people who have symptoms.

Chlamydia is tested with a nucleic acid amplification test (NAAT). A swab of fluid will be taken from the penis, cervix, throat, or rectum. A urine sample may also be taken. The sample will be tested to look for signs of infection.
