What are gonorrhea and chlamydia tests?
These tests use a sample of urine or other body fluid to look for the bacteria that cause these sexually transmitted infections (STIs). The fluid sample can come from the cervix, vagina, rectum, throat, or eyes.
Why are gonorrhea and chlamydia tests done?

How are gonorrhea and chlamydia tests done?
- For a direct sample, a swab is used to collect body fluid from the cervix, vagina, rectum, throat, or eyes. Your doctor may collect the sample. Or you may be given instructions on how to collect your own sample.
- For a urine sample, you will collect the urine that comes out when you first start to urinate. Don't wipe the genital area clean before you urinate.
How do you prepare for gonorrhea and chlamydia tests?
- If you are going to have a urine test, do not urinate for at least 1 hour before the test.
