Why Is This Test Done?

Your healthcare provider may recommend this test if you have symptoms like pain, discharge, or bleeding in the rectal area, or if you’ve been exposed to gonorrhea. It’s also used to monitor treatment effectiveness or check for infections in areas not typically tested (like the rectum).

What Does the Test Involve?

A healthcare professional will collect a sample from your rectum using a sterile swab. The swab is then sent to a lab to grow bacteria in a controlled environment. Results typically take 2–5 days, depending on lab processes.

What Does a Positive Result Mean?

A positive result means *Neisseria gonorrhoeae* was found in your sample. This confirms a gonorrhea infection and is essential for starting appropriate antibiotic treatment. Always follow your provider’s guidance for care.

What Does a Negative Result Mean?

A negative result means no bacteria were detected in this sample. However, it doesn’t guarantee you’re completely free of gonorrhea—other areas (like the throat or urethra) may still be infected. Follow-up testing or retesting may be recommended.

Frequently asked questions

Early detection of gonorrhea is critical because untreated infections can lead to serious health complications, such as pelvic inflammatory disease (in women), infertility, or joint/septic infections. Rectal gonorrhea can also spread to other parts of the body or increase the risk of HIV transmission.
This test is used primarily for diagnosing infections in the rectal area. It’s not a screening test for general gonorrhea exposure and may miss infections in other body sites. Always discuss your symptoms and risk factors with your healthcare provider to determine the best approach for testing and treatment.
How often should I get tested for gonorrhea if I’m sexually active?
The CDC recommends routine gonorrhea testing for sexually active individuals aged 15–64 who have multiple partners or new partners. If you have symptoms or a history of exposure, testing is especially important. Your provider may adjust recommendations based on your situation.
Can I still have gonorrhea even if I don’t have symptoms?
Yes, gonorrhea can be asymptomatic (no symptoms) in some people, especially in men or women with infections in non-typical areas like the rectum. That’s why testing is crucial, even if you feel well. Always follow your provider’s advice for testing and treatment.
