Chlamydia and Gonorrhea Test: One Test for Both

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

Quick answer

Yes. A single urine sample or swab can be tested for both chlamydia and gonorrhea at once, and the CDC recommends the same kind of test (a NAAT) for each. The CDC recommends yearly screening for both infections in sexually active women under 25 and in men who have sex with men. A standard urine or vaginal sample does not check your throat or rectum, so ask for those swabs if you had oral or anal sex.

The test you need

Chlamydia: NAATRetest if negative before day 49

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

Which of these apply to you?

I am under 25, sexually active, and have a vagina
I am a gay or bisexual man, or I have sex with men
A partner has been told they have chlamydia or gonorrhea
I had oral or anal sex and want those sites checked
I am pregnant, or planning to be, and want to ask about testing

The CDC recommends yearly testing for chlamydia and gonorrhea for sexually active women under 25 and for men who have sex with men. This list is a guide to the conversation, not a diagnosis.

Chlamydia and gonorrhea often cause no symptoms, and both are tested for with a NAAT. That is why they are often checked together, from a single sample.

Is there one test for both chlamydia and gonorrhea?

Yes. The CDC recommends a NAAT (nucleic acid amplification test) for both infections, and the sample types it lists for each include first-void urine, vaginal swabs, and swabs of the throat or rectum.

You will see this in a few places:

Clinics and labs. Ask whether the clinic can test both from one urine or swab sample.
Online lab ordering. STDCheck’s panel page describes one panel for both infections, using a small urine sample.
Home collection. The FDA authorized a home-collection test for both in 2023, where you mail a sample to a lab. In 2025 it authorized a home test for chlamydia, gonorrhea and trichomoniasis, with results in about 30 minutes, intended for females.

Who should get both tests?

The CDC recommends yearly screening for both infections for sexually active women under 25, and for men who have sex with men, at the sites of contact. For gonorrhea, the CDC also advises screening women 25 and older who are at increased risk. Anyone with symptoms, or with a partner who has been told they have either infection, should be tested too.

For pregnancy, the CDC says all pregnant women under 25 should be screened for chlamydia. Ask your prenatal provider about gonorrhea testing.

Does the test cover my throat and rectum?

Not unless they are swabbed. A urine or vaginal sample checks the genital and urinary tract. The CDC says infection at the throat or rectum is diagnosed by testing those sites, and gonorrhea of the throat usually has no symptoms.

STDCheck’s panel page says gonorrhea can also grow in the mouth, throat, anus and eyes, but it does not say whether the panel tests those sites. If you had oral or anal sex, ask a clinician for throat and rectal swabs.

When should I test after exposure?

The CDC does not give a single waiting time for either infection. STDCheck’s pages suggest about two weeks after exposure. MedlinePlus says gonorrhea may take weeks to test positive. If you want the cautious answer, use the longer wait, and repeat a negative result if you tested early.

Don’t wait if a partner has been told they have either infection. See a clinician.

How long do results take?

STDCheck’s page says results are ready in 1 to 2 days. MedlinePlus says chlamydia results are usually ready in a day, with some rapid tests giving results in 90 minutes or less. Mailed home kits depend on shipping and lab time. See how long STD results take.

Do I need to prepare for the test?

For a urine sample, yes. MedlinePlus says to avoid urinating for two hours before a first-catch chlamydia urine sample. Your clinic or lab will give you its own instructions, so follow those. Don’t stop any medicine without asking your clinician first.

Can a combined test be wrong?

Yes, like any test. A NAAT is the most sensitive type, according to the CDC, but a test taken very soon after exposure can miss an infection. For home-collection tests, the FDA names false negatives and false positives as risks. A negative result means the infections were not found in that sample at that time. If you have symptoms or a new exposure, talk to a clinician.

What happens if I test positive?

Both infections are treated with antibiotics prescribed by a clinician. The CDC says to retest about 3 months after treatment for each, and that recent partners should be evaluated and treated. For gonorrhea of the throat, it advises a test of cure 7 to 14 days after treatment.

The FDA says that for home tests, a positive result should lead to medical care, and a negative result with symptoms or recent exposure should lead to a conversation with a provider.

Get care now if

You are pregnant and think you may have been exposed, or a test came back positive
You have pelvic or lower belly pain with fever, or pain or swelling in the testicles
You have a new discharge or burning when you pass urine
Your symptoms are not improving after 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 either infectionSee a clinician soon. The CDC says recent partners should be referred for evaluation, testing and presumptive treatment.
After a possible exposure, with no symptomsThe CDC gives no set waiting time. STDCheck's gonorrhea page says to wait 2 weeks, and MedlinePlus says gonorrhea may take weeks to test positive. If you test earlier, repeat a negative.
Once a year, if you are in a screening groupThe CDC advises yearly screening for sexually active women under 25 and for men who have sex with men.
About 3 months after treatmentThe CDC says anyone treated for either infection should be retested 3 months later.

Common questions

Do I need two separate tests for chlamydia and gonorrhea?

Not usually. A combined test checks one sample for both. STDCheck sells a Chlamydia & Gonorrhea panel, and the FDA has authorized home-collection kits that test for both.

What if only one of the two is positive?

A clinician will advise treatment for whichever infection is found. The CDC says anyone treated for either infection should be retested about 3 months later, and that recent partners should be evaluated and treated.

Does the combined test check my throat?

A standard urine or vaginal sample does not. The CDC says throat and rectal infections are found by testing those sites. STDCheck's page for its panel does not say whether it tests them, so ask a clinician for swabs if you had oral or anal sex.

Is this test the same as a full STD panel?

Not necessarily. A full STD panel may test for other infections as well. Check exactly which infections are included before you order.

Next: Combined chlamydia and gonorrhea NAAT.
