Why This Test Matters

Gonorrhea is a common STI that can lead to serious health problems if untreated, including pelvic inflammatory disease, infertility, or complications during pregnancy. Early detection helps prevent these risks.

How the Test Works

This test uses an immunoassay method to identify gonorrhea bacteria in your genital secretions (e.g., urine, vaginal fluid, or cervical fluid). A positive result means bacteria are present, but it does not confirm the cause of symptoms.

What to Expect Before the Test

You may be asked to provide a sample (e.g., urine or swab) from your genital area. Follow your healthcare provider’s instructions to ensure accuracy.

What to Expect After the Test

Results are typically ready within 24–48 hours. If positive, follow-up testing or treatment will be recommended based on your healthcare provider’s guidance.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A positive result indicates gonorrhea infection and requires immediate treatment with antibiotics. Untreated gonorrhea can spread to other parts of the body, affect fertility, or lead to complications in pregnancy. A negative result means no bacteria were detected in this sample, but retesting may be needed if symptoms persist.

Frequently asked questions

How often should I get tested for gonorrhea?
The frequency depends on your risk factors. Healthcare providers often recommend testing annually for sexually active individuals with multiple partners or if you’ve had unprotected sex with someone infected. If you suspect symptoms, testing is urgent.
What does a positive result mean for my health?
A positive result means you have gonorrhea and should start treatment right away. Your provider will prescribe antibiotics to clear the infection. Even if you feel well, untreated gonorrhea can cause long-term health issues, so follow all treatment instructions.
Can I still have sex while waiting for test results?
No, it’s important to avoid sexual contact until you’ve completed treatment and your provider confirms the infection is cleared. This helps prevent spreading gonorrhea to others.
