Your healthcare provider may order this test to help identify an underlying condition, confirm a suspected diagnosis, or check how well a treatment is working. It gives your care team important information that helps guide decisions about your ongoing care.
Your healthcare provider may recommend this test if you have symptoms like painful urination, unusual discharge, or if you’re at higher risk for gonorrhea (e.g., sexually active, recent exposure). It’s also used for screening in sexually transmitted infection (STI) clinics or during pregnancy to prevent complications.
The test looks for specific markers in your body that can signal a particular health condition. Your sample is analyzed in a laboratory using validated methods, and the presence, absence, or amount of these markers helps your provider understand your health status.
The test uses a molecular method (PCR) to identify tiny amounts of gonorrhea bacteria’s genetic material in your urine. No blood draw is needed—just a urine sample is collected and tested in a lab.
Depending on the type of test, a small sample such as blood, urine, or a swab from the affected area may be needed. A trained healthcare professional will collect the sample, which usually takes only a few minutes, and then send it to the laboratory for analysis.
You’ll provide a midstream urine sample (a small amount of urine collected midstream during urination). Follow your provider’s instructions carefully to ensure accuracy.
Once the laboratory completes the analysis, your results are sent to your healthcare provider, who will explain what they mean for you. Results may be normal or abnormal, and your provider will discuss any follow-up testing, treatment, or monitoring you may need.
Results are typically ready within 1–2 days. A positive result means gonorrhea is likely present, while a negative result means it’s not detected in this sample. Follow-up testing or treatment may be recommended based on your symptoms and risk factors.

Frequently asked questions
This test is highly sensitive and specific for diagnosing gonorrhea, especially in asymptomatic individuals or those without obvious symptoms. Early detection allows for prompt treatment to prevent complications like pelvic inflammatory disease, infertility, or spread to others.
A positive result confirms gonorrhea infection in your urine sample. You’ll need to see a healthcare provider for treatment with antibiotics tailored to the bacteria. Treatment may also include partners to prevent reinfection.
Yes, rare false negatives can occur if the sample isn’t collected properly or if the bacteria are present but not detected in this urine sample. If you have symptoms, repeat testing or other diagnostic methods may be needed.
