How to Test for Gonorrhea (Urine, Swab and Throat)

By Richard D. Porter, Patient Advocate Updated October 26, 2026

Quick answer

Gonorrhea is usually tested with a NAAT on a urine sample or a vaginal swab. If you had oral or anal sex, you may need a swab of your throat or rectum. The CDC says pharyngeal (throat) testing should be done when oral sexual exposure is reported. The CDC gives no fixed waiting time after exposure, and MedlinePlus says it may take weeks to test positive, so a negative test soon after exposure may need repeating. If a partner has gonorrhea, see a clinician instead of waiting.

The test you need

Gonorrhea: NAATRetest if negative before day 49

Too earlyMay detect; retest if negativeReliable

Counted from your most recent exposure. CDC gives no single window for chlamydia, gonorrhea, trich or syphilis; the cautious date uses the NHS "up to 7 weeks". Work out your own dates

Test: Gonorrhea NAAT (urine or swab)
Sample: First-void urine or a vaginal swab; a throat or rectal swab if those sites were exposed
When: The CDC gives no fixed waiting time. MedlinePlus says it may take weeks to test positive after infection, so repeat an early negative
Results: STDCheck's gonorrhea page says results are ready in 1 to 2 days

Which of these apply to you?

I had oral sex and want my throat checked
I had anal sex and want my rectum checked
A partner has been told they have gonorrhea
I am under 25, sexually active, and have a vagina
I am a gay or bisexual man, or I have sex with men

The CDC recommends yearly gonorrhea screening for sexually active women under 25 and for men who have sex with men, at the sites of exposure. This is a guide to the conversation, not a diagnosis.

Gonorrhea often has no symptoms, according to MedlinePlus, so a test is how you find out. What matters is choosing the right sample for the kind of sex you had, and getting the timing right.

How do you test for gonorrhea?

The test the CDC describes is a NAAT (nucleic acid amplification test), which looks for the bacteria’s genetic material. The CDC says NAAT sensitivity for gonorrhea at genital and non-genital sites is superior to culture.

Samples depend on your anatomy and the sex you had:

Urine. For men, the CDC lists first-void urine as an optimal sample.
Vaginal swab. For people with a vagina, the CDC lists a vaginal swab as an optimal sample.
Throat or rectal swab. After oral sex, the CDC says throat testing should be done when oral exposure is reported. For high-risk men who have sex with men, the CDC advises screening at all anatomic sites of exposure.

The CDC says patient-collected samples can be used in place of provider-collected samples in clinical settings, after patient instructions have been provided.

How do you test for oral gonorrhea?

With a throat swab. The CDC says the majority of gonococcal infections of the pharynx are asymptomatic, so a lack of a sore throat tells you little. It also says that if oral sexual exposure is reported, pharyngeal testing should be performed.

If you had oral sex and want to be sure, ask the clinic whether it does throat swabs before you book. STDCheck’s gonorrhea page describes a urine test and does not mention throat or rectal testing, so a clinician is the better route for those sites.

Can you test for gonorrhea at home?

Partly. The CDC says FDA-approved self-collection testing options are available for gonorrhea. MedlinePlus says some kits include a urine container and you send the sample to a lab. The FDA has authorized home-collection kits that test for both chlamydia and gonorrhea, using vaginal swabs or urine. See chlamydia and gonorrhea tests.

The home kits the FDA describes use vaginal swabs or urine, so the sample types listed do not include throat or rectal sites. If those were exposed, a clinic visit is the better route. Check each kit’s instructions.

How long after exposure can gonorrhea be detected?

The CDC does not give a single waiting time. MedlinePlus says that after you are infected it may take weeks before you test positive, and that a test taken too soon after exposure can be negative when infection is present. STDCheck’s gonorrhea page suggests waiting 2 weeks after potential exposure for more accurate results.

If you test early and get a negative, ask whether to repeat. If a partner has been told they have gonorrhea, don’t wait for a test: the CDC says recent partners should be referred for evaluation, testing and presumptive treatment.

How long do gonorrhea test results take?

It depends on the lab and the type of test. STDCheck’s gonorrhea page says results are ready in 1 to 2 days. For a clinic test, ask when and how you will hear back, and what to do if you have not heard. A mailed home kit adds shipping time, because the sample has to reach the lab first.

Who should be tested for gonorrhea?

The CDC recommends annual screening for sexually active women under 25 and at least annual screening for men who have sex with men. It advises screening older women at increased risk. For heterosexual men and women over 25 who are at low risk, the CDC says screening is not recommended. Anyone with symptoms or a partner with gonorrhea should see a clinician for testing.

If you are pregnant, tell your provider. The CDC guidance includes specific treatment advice for gonorrhea in pregnancy, so ask your prenatal provider about testing.

What happens after a positive result?

Gonorrhea is treated with antibiotics prescribed by a clinician. The CDC notes that gonorrhea’s susceptibility to some antimicrobials is decreasing, which is why follow-up matters. NAATs cannot provide antimicrobial susceptibility results, and culture is used when treatment failure is suspected or documented.

Retest 3 months after treatment, according to the CDC. If you had a throat infection, return 7 to 14 days after treatment for a test of cure. Tell recent partners so they can be tested and treated.

Get care now if

You have pain or swelling in the testicles, or pelvic or lower belly pain with fever
You have a new discharge or burning when you pass urine
You are pregnant and think you may have been exposed
Your symptoms are not improving after you finish treatment

Call 911 for a medical emergency. Otherwise, an urgent care clinic, sexual health clinic or your doctor can see you.

When to test

If a partner has been told they have gonorrheaSee a clinician soon. The CDC says recent sex partners should be referred for evaluation, testing and presumptive treatment.
After a possible exposure, no symptomsThe CDC gives no set waiting time. STDCheck's gonorrhea page says its doctors recommend waiting 2 weeks after potential exposure, and MedlinePlus says it may take weeks to test positive. Repeat an early negative.
Once a year, if you are in a screening groupThe CDC advises annual gonorrhea screening for sexually active women under 25 and for men who have sex with men.
After treatmentThe CDC says anyone treated for gonorrhea should be retested 3 months later. For a throat infection, it advises a test of cure 7 to 14 days after treatment.

Common questions

How do they test for gonorrhea?

Urine is one option, and vaginal swabs are also used. For oral sex, the CDC says throat testing should be done when oral exposure is reported. The CDC says patient-collected samples can be used in place of provider-collected ones when instructions have been given.

Can I test for gonorrhea at home?

Some options exist. The CDC says FDA-approved self-collection testing options are available for gonorrhea, and MedlinePlus says some kits use a urine container that you send to a lab. They do not cover every sample site, so ask a clinician if you need throat or rectal testing.

Does a urine test check my throat?

A urine sample is not a throat sample. The CDC says that if oral sexual exposure is reported, pharyngeal testing should be performed, and that most gonococcal infections of the pharynx are asymptomatic. If you had oral sex, ask for a throat swab.

Do I need a test of cure?

For throat infection, yes. The CDC says anyone with gonorrhea of the throat should return 7 to 14 days after initial treatment for a test of cure. For other sites, ask your clinician.
