Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like unusual discharge, pain during urination, or other signs of infection. It’s also used to confirm a gonorrhea diagnosis in people who test positive for other sexually transmitted infections (STIs) or have risk factors for infection.

How the Test Is Performed

A swab sample is collected from the genital area (e.g., urethra, cervix, or rectum) and sent to a lab. The sample is cultured to grow bacteria in a controlled environment over time.

What to Expect Before the Test

No special preparation is needed. You may shower or clean the area gently before the test, but avoid using soaps or lotions that could interfere with results.

What to Expect During the Test

The swab is inserted gently into the affected area, and you may feel mild discomfort or pressure. The procedure takes only a few minutes.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive culture confirms gonorrhea and guides treatment with appropriate antibiotics. It helps monitor infection spread, track antibiotic resistance, and ensure proper follow-up care. A negative result means no *N. gonorrhoeae* was detected in the sample, but other STIs or infections may still be present.

Frequently asked questions

How long does it take to get results?
Results typically take 2–5 business days, depending on lab processing times. Your provider will contact you once results are available.
What does a positive result mean?
A positive result means *Neisseria gonorrhoeae* bacteria were found in your sample. This requires immediate treatment with antibiotics to clear the infection and prevent complications like infertility or joint infections.
Can I have sex while waiting for results?
No, avoid sexual contact until you’ve completed treatment for gonorrhea and your provider confirms the infection is cleared. Always use protection if you’re sexually active during this time.
