Gonorrhea Test: How It Works and When to Get One

What a Gonorrhea Test Detects

A gonorrhea test looks for Neisseria gonorrhoeae, the bacterium that causes the infection commonly called the clap. It spreads through sexual contact and can infect the genitals, rectum, and throat. Many people carry it without any symptoms, which means testing is the only reliable way to know your status.

How the Test Works

The standard test is a nucleic acid amplification test, or NAAT, which detects the bacterium's DNA. A first-catch urine sample is common for genital testing. A swab of the throat or rectum is used when exposure happened in those areas, because a urine test will not detect an infection that sits elsewhere.

No fasting is needed, and no medication changes are required. For a urine sample, hold your urine for about one to two hours beforehand so the sample is concentrated.

When to Get Tested

Gonorrhea has a short window period. A NAAT can typically detect infection about one to two weeks after exposure. Testing earlier can miss the infection, so if you had a known exposure, wait at least two weeks before collection.

Routine screening is recommended once a year for sexually active women under 25 and for adults with risk factors. Pregnant women are often screened as well, because treatment prevents passing the infection to a newborn during delivery.

How Accurate Is It

NAAT testing is considered highly accurate when the right sample is collected from the right site. A negative result taken too early should be repeated. A positive result should prompt treatment and partner notification. Retesting after treatment is often advised because some strains have developed resistance to older antibiotics.

How to Order and Where to Get Tested

You can order a gonorrhea test online and give your sample at a local patient service center. No doctor visit is required. Collection sites are available in most metro areas, including Chicago, Houston, and Atlanta, and a home kit is an option in some programs.

How Much Does It Cost

A single gonorrhea test commonly costs about $50 to $120. Because chlamydia and gonorrhea are so often tested together, a combined test is frequently the better value and adds little to the total price.

Results and Treatment

Results usually arrive in one to three business days. Gonorrhea is treatable with antibiotics selected by a clinician. Finish the full course, avoid sex until you and your partner are cleared, and get retested afterward to confirm the infection has cleared, since resistance is a growing concern.

Gonorrhea and Antibiotic Resistance

Gonorrhea has developed resistance to several antibiotics that were once used to treat it, which is why current guidance uses a specific recommended regimen and why retesting matters. Taking antibiotics that were not prescribed, or stopping early, gives the bacterium a chance to survive and adapt. Always complete the exact course a clinician provides.

Why the Collection Site Matters

Gonorrhea can settle in the throat or rectum after oral or anal sex, and those infections often cause no symptoms. A urine test will not find them. If your exposure included those sites, ask for a swab so the sample is collected where the bacteria actually are. Getting the site right is just as important as getting the timing right.

What the Results Mean

A negative result means the bacterium was not detected in the sample you provided. If the sample was collected before the window period ended, repeat testing is needed. A positive result means the infection is present and should be treated promptly, with partners notified so they can be tested too.

After Treatment

Most people feel better within days, but the infection is not necessarily gone the moment symptoms fade. A test of cure is often recommended, especially when resistance is a concern. Return for care if symptoms persist or come back after treatment.

Lowering Your Risk

Condoms reduce the chance of gonorrhea, including at the throat and rectum. Regular screening and honest conversations with partners add another layer of protection. If you are diagnosed, avoiding sex until treatment is complete keeps the infection from spreading further.

Testing Your Partners

Sex partners should be tested and treated so the infection does not bounce back. Some clinics offer patient-delivered therapy, where you bring medication to a partner, while others require the partner to be seen. Ask what your local clinic allows, and avoid sex until everyone is cleared.
