Quick Guide

The chlamydia and gonorrhea panel tests for both bacterial infections at once from a single urine sample. A nucleic acid amplification test (NAAT) detects the DNA of each organism, identifying active infections with high accuracy.

If you’ve had a possible exposure, test promptly. NAAT can reliably detect both infections about one to two weeks after exposure. A negative result earlier than two weeks doesn’t rule out infection. If your first result is negative and you had a confirmed exposure, retest after the window closes.

Both infections are often asymptomatic. NAAT detects active, current infections only, not past ones that have cleared. No fasting is required.

About the Chlamydia and Gonorrhea Test

Purpose of the test

This panel checks for active chlamydia and gonorrhea infections together. Testing both at once is standard practice because the two infections share the same transmission routes and frequently co-occur. When symptoms do show up, they overlap enough that testing separately can slow diagnosis.

Most people with either infection don’t have symptoms. That’s why testing is the only reliable way to know your status. Untreated chlamydia infections can lead to pelvic inflammatory disease (PID), infertility, ectopic pregnancy, and epididymitis (in males), as described in CDC gonorrhea and chlamydia complication guidance. Gonorrhea can also affect the rectum, eyes, throat, and joints.

The panel serves three purposes:

  • Screening: The CDC recommends annual screening for sexually active people at higher risk, even without symptoms.
  • Diagnosis: Consider this test if you have unusual discharge, burning urination, or pelvic pain.
  • Monitoring: Retest three months after finishing treatment to catch reinfection from an untreated partner or new exposure.

The panel doesn’t detect syphilis, HIV, herpes, trichomoniasis, or other STIs, for broader coverage, see STD testing options. It won’t identify past infections that have cleared. It also can’t detect antibiotic resistance. A culture is needed for that.

What does the chlamydia and gonorrhea test measure?

This panel covers two markers from a single urine sample processed at a Clinical Laboratory Improvement Amendments (CLIA)-certified lab.

Other Markers

  • Chlamydia trachomatis: Detects the DNA of the bacterium that causes chlamydia, showing an active urogenital infection.
  • Neisseria gonorrhoeae: Detects the DNA of the bacterium that causes gonorrhea, showing an active urogenital infection.

NAAT is the gold standard for detecting both infections. It’s the most accurate molecular method for urogenital samples, and it’s what most CLIA-certified labs use. According to the National Library of Medicine, urine NAAT is widely accepted for diagnosing urogenital chlamydia in both men and women. A urine NAAT detects only urogenital infections, but not throat and rectal infections. These require a swab collection of each area that is tested by NAAT technique. The swabs must be collected at a clinic.

Providers have other testing methods for specific situations:

  • Swab NAAT: Same DNA detection method, different sample site. Required for throat or rectal infections.
  • Gonococcal culture: Grows Neisseria gonorrhoeae from a swab of the infected site to test which antibiotics work using antimicrobial sensitivity testing. Used when resistant gonorrhea is suspected.
  • Chlamydia culture: Though less often used because the process is complex, it is used for legal/forensic cases and antimicrobial sensitivity testing when antibiotics fail to work.
  • Gram stain: A quick microscope test that can spot gonorrhea in men with urethral symptoms. Less accurate for other sites and not used for chlamydia.
  • Blood testing: Not the standard approach for either infection. Both bacteria live in the genital tract tissue, not the bloodstream. Urine or swab NAAT is more accurate.

When should I get a chlamydia and gonorrhea test?

Consider testing if any of these apply:

  • A possible exposure to chlamydia or gonorrhea
  • A prior STI diagnosis
  • A sexual partner recently diagnosed with an STI
  • Burning urination, pelvic pain, or unusual genital discharge
  • Current pregnancy
  • Inconsistent condom use during vaginal, anal, or oral sex
  • A new sex partner or multiple sex partners

For routine screening, the U.S. Preventive Services Task Force recommends annual testing for:

  • All sexually active women under 25
  • Women 25 and older with risk factors (new partner, multiple partners, partner with an STI)
  • Gay, bisexual, and other men who have sex with men (MSM) at all exposed sites; every three to six months if at higher risk
  • Pregnant women at the first prenatal visit; rescreen in the third trimester if under 25 or at higher risk
  • Anyone diagnosed with HIV, at the first evaluation and at least annually thereafter

Urine NAAT works for urogenital infections in both men and women. If you’re concerned about throat or rectal exposure, ask about swab testing at a clinic.

How It Works

How to get tested

This test is ordered through a healthcare provider, clinic, or hospital lab. CLIA-certified labs, including LabCorp and Quest Diagnostics, process most U.S. tests of this type. Your provider sends the order to a partner lab where you provide a urine sample at the patient service center or the provider’s office. Results come back within one to three business days.

Prefer to test privately from home? Both infections are included in an at-home STD test. These kits screen for chlamydia, gonorrhea, and other STIs from a self-collected urine or swab sample. Kits include instructions, collection materials, and prepaid shipping, with results delivered through a secure online portal. If you’re concerned about a throat or rectal infection, though, a clinic swab is needed. An at-home urine kit won’t cover those sites.

Before the test

  • No fasting required. Eat and drink normally.
  • Don’t urinate for at least one to two hours before your appointment. This keeps enough bacterial DNA concentrated in the sample.
  • Avoid genital cleaning products or douches before the test. They can interfere with results.
  • Tell your provider about any antibiotics you’re taking. Antibiotic use can suppress bacterial DNA and affect accuracy.
  • Bring a list of current medications and any relevant medical history.

First-catch urine is what the lab needs. That’s the very first part of your stream, not midstream. Bacterial concentration is highest there. You’ll get instructions at the collection site, but knowing this ahead of time helps.

During the test

  • Check in at the patient service center with a photo ID and your order confirmation.
  • A staff member gives you a sterile cup and directs you to a private restroom.
  • Begin urinating and collect the first part of the stream into the cup. Fill it to the indicated line.
  • Seal and label the cup, then hand it to the lab staff.

That’s it. No blood draw, no swab for a standard urine NAAT. Collection takes a few minutes and is painless.

If your provider ordered a swab for throat or rectal testing, a technician takes the swab at the clinic. It’s brief. A few seconds of mild discomfort at most.

No recovery time is needed. You can leave right away. If you have severe symptoms, unusual pain, fever, or joint pain before or after testing, contact your provider.

After the test

Results are typically ready within one to three business days after the lab receives your sample, though timing can vary by lab. They’ll come through your provider’s patient portal or office. You don’t need to do anything else while you wait.

What Do My Results Mean?

Your report shows two separate results: one for Chlamydia trachomatis and one for Neisseria gonorrhoeae. Each is reported as detected or not detected.

If your results are negative

No DNA from either organism was found. For most people, that’s a clear negative result.

But timing matters. If you tested within one to two weeks of a possible exposure, the infection may not have been detectable yet. If you had a confirmed exposure or symptoms continue, retest after the window closes.

A negative result from this panel doesn’t test for other STIs either. If you were concerned about throat or rectal exposure, a urine test can’t rule out infection at those sites. A swab NAAT at a clinic is needed.

If your results are positive

One or both infections were detected. Both are curable with antibiotics. Chlamydia is generally treated with doxycycline. Gonorrhea is treated with ceftriaxone, per CDC gonorrhea treatment guidelines. Your provider prescribes based on your full clinical picture.

Avoid sexual activity until you and any partners finish treatment. Neither infection gives you lasting immunity. Reinfection is possible after re-exposure. The National Library of Medicine’s gonorrhea test overview notes that retesting three months after treatment is standard practice to catch reinfection.

Notify recent sexual partners so they can get tested and treated. This step is what prevents reinfection.

If a positive result was unexpected, ask your provider about confirmatory testing. A second NAAT or culture can rule out a false positive before treatment begins. If gonorrhea is detected and antibiotic resistance is a concern, your provider may order a gonococcal culture.

FAQs

Does a Pap smear test for chlamydia and gonorrhea?

No. A Pap smear collects cervical cells to screen for cervical cancer and HPV (human papillomavirus). It doesn’t include chlamydia or gonorrhea testing. A separate NAAT order is needed.

Can you test for chlamydia and gonorrhea with a blood test?

No. Blood isn’t the standard method for either infection. Both bacteria live in the genital tract tissue, not the bloodstream, so urine or swab NAAT is required. Blood tests aren’t routinely used or recommended for diagnosing chlamydia or gonorrhea, but are appropriate for other STIs (e.g., syphilis, HIV, hepatitis).

Can you have both chlamydia and gonorrhea at the same time?

Yes. Co-infection is common because both share the same transmission routes. That’s why providers test for both together. Each infection requires a different antibiotic.

Is the chlamydia and gonorrhea urine test accurate for both men and women?

Yes. NAAT on a urine sample detects both infections in men and women with urogenital infections. For women, a vaginal swab NAAT is slightly more sensitive than urine, but urine testing is widely accepted. The test works for both sexes.

How long after treatment should I retest?

Retest three months after finishing treatment for both chlamydia and gonorrhea. This catches reinfection from an untreated partner or a new exposure. If symptoms return before three months, retest sooner.

Can this test detect throat or rectal chlamydia and gonorrhea?

No. A urine NAAT detects urogenital infections only. Throat and rectal infections require a swab NAAT collected at a clinic. If you’re at risk for infections at those sites, inform your provider, who will swab other infected areas.
