The standard test for gonorrhea in men is a urine-based molecular test called a nucleic acid amplification test (NAAT). It’s the most sensitive and accurate method available, and in most cases, all you need to do is pee in a cup. Results typically come back within one to three days.
The Urine Test: What It Involves
For men, the optimal specimen is a “first-catch” urine sample, meaning the first part of your urine stream rather than a midstream sample. You’ll urinate directly into a specimen cup until it’s about one-third full, then pass the rest into the toilet. The lab runs a NAAT on this sample, which detects the genetic material of the gonorrhea bacteria with high accuracy.
There’s one key preparation step: don’t urinate for at least 20 minutes before the test. This gives the bacteria enough time to accumulate in the urethra so the first-catch sample picks them up. You also shouldn’t clean or wipe your genitals beforehand. Beyond that, no fasting, no special diet, no complicated prep.
When Swab Tests Are Needed
A urine test only detects gonorrhea in the urethra. If you’ve had oral or anal sex, those sites need to be tested separately with swabs, because gonorrhea in the throat or rectum won’t show up in urine. A throat swab and a rectal swab are each quick, taking just a few seconds, and are processed with the same NAAT technology.
Pharyngeal (throat) gonorrhea is particularly easy to miss. Research on men who have sex with men found that pharyngeal gonorrhea was actually more common than urethral or rectal infections, with a prevalence of about 5.5% in the study group. There was no correlation between having throat symptoms and testing positive, meaning you can carry it without a sore throat or any discomfort at all. This is why CDC guidelines recommend that sexually active men who have sex with men get tested at all sites of contact (urethra, rectum, and throat) at least once a year, regardless of condom use, and every three to six months if at increased risk.
For heterosexual men at low risk, the CDC notes there isn’t enough evidence to recommend routine screening. Testing is still warranted if you have symptoms, a partner tests positive, or you have a new risk factor.
How Soon After Exposure You Can Test
NAAT testing can detect gonorrhea without waiting a full 48 hours after exposure, because the molecular test is sensitive enough to pick up small amounts of bacterial genetic material even early on. Older culture-based tests required at least a 48-hour window to avoid false negatives, but NAATs don’t have this limitation. That said, many clinics suggest waiting about five days for the highest confidence in results, since bacterial load increases as infection establishes. If you test very early and get a negative result but still have concerns, a follow-up test a week or two later can rule it out more definitively.
Symptoms to Watch For
Most men with urethral gonorrhea do develop noticeable symptoms within two to five days of infection. The classic signs are a burning sensation when urinating and a white, yellow, or greenish discharge from the penis. Swollen or painful testicles can also occur, though less commonly.
Rectal gonorrhea may cause discharge, itching, soreness, or pain during bowel movements, but it can also be entirely silent. Throat infections are almost always asymptomatic. The takeaway: symptoms are a reason to get tested, but a lack of symptoms is not a reason to skip testing if you’ve had a potential exposure.
Understanding Your Results
NAAT results are straightforward: positive or negative. Most labs return results in one to three days, depending on whether the lab is on-site or samples are sent out. A positive result means the bacteria’s genetic material was detected in your sample. A negative result means it wasn’t, though testing too early after exposure can occasionally produce a false negative.
If your urine test is positive, your provider may also perform a bacterial culture. Cultures are less sensitive than NAATs for initial diagnosis, but they allow the lab to test which antibiotics the bacteria respond to. This matters because antibiotic-resistant gonorrhea is a growing concern, and culture-based susceptibility testing helps guide treatment if the standard approach doesn’t work.
What Happens After a Positive Test
Treatment for uncomplicated gonorrhea (urethral, rectal, or throat) is a single injection of an antibiotic, typically given the same day or shortly after results come in. The infection clears quickly in most cases, and you’ll be advised to avoid sex for seven days after treatment.
Your sexual partners need treatment too. The standard approach is for partners to be examined and treated by their own provider, but when that’s not realistic, many states allow something called expedited partner therapy. This means your clinician can provide a prescription or medication for you to give directly to your partner without them needing their own appointment first. It’s not the ideal method, since the partner misses out on a full evaluation, but it’s far better than leaving a partner untreated and risking reinfection.
A follow-up test about three months after treatment is recommended to check for reinfection, which is common. This isn’t to confirm the treatment worked (the single injection is highly effective) but to catch new infections from untreated partners or new exposures.
Where to Get Tested
Gonorrhea testing is available at your primary care doctor’s office, urgent care clinics, sexual health clinics, and local public health departments. Many cities also have free or low-cost STI testing sites. At-home NAAT kits that let you collect a urine sample and mail it to a lab are increasingly available, though they typically only test the urethral site. If you need throat or rectal testing, an in-person visit is necessary.
