Why This Test Matters

Gonorrhea is a sexually transmitted infection (STI) that can cause serious health problems if untreated, including pelvic pain, infertility, or complications during pregnancy. Early detection helps prevent these issues and allows for prompt treatment.

How the Test Works

The test detects specific proteins (antigens) from *N. gonorrhoeae* bacteria in your urine using a sensitive immunoassay method. No blood draw is required—just a urine sample.

Sample Collection

You’ll provide a midstream urine sample (a small amount of urine collected directly from your bladder). This is a quick, painless process, often done at home or during a clinic visit.

What to Expect After the Test

Results are typically available within 24–48 hours. If positive, your healthcare provider will guide you on next steps, including treatment options.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result indicates *N. gonorrhoeae* bacteria are likely present in your urine, suggesting gonorrhea. However, further testing (e.g., culture) may be needed to confirm the diagnosis and guide treatment.
Can I still have gonorrhea if my test is negative?
Yes, a negative result means no detectable bacteria in this sample, but gonorrhea could still be present elsewhere in your body (e.g., cervix, urethra). Follow-up testing may be recommended if symptoms persist or you suspect exposure.
How can I prevent gonorrhea?
Use condoms during sex, limit sexual partners, and get tested regularly if you’re sexually active. Vaccination against hepatitis B (not gonorrhea) is also recommended for protection against other STIs.
