What This Test Measures

The test detects the presence of *Neisseria gonorrhoeae* bacteria in your vaginal secretions. It’s not a blood test or antibody test but a direct culture to identify live bacteria.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like unusual vaginal discharge, pain during urination, or other signs of infection. It’s also used for screening in high-risk groups or after exposure to gonorrhea.

How the Test Works

A swab sample is collected from your vaginal area and sent to a lab. The sample is grown in a controlled environment to see if *Neisseria gonorrhoeae* bacteria multiply, confirming an infection if present.

Preparation

No special preparation is needed. You may shower or clean the vaginal area before the test, but avoid using douches, vaginal creams, or tampons on the day of testing.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Frequently asked questions

This test is critical for diagnosing gonorrhea, a sexually transmitted infection (STI) caused by *Neisseria gonorrhoeae*. Untreated gonorrhea can lead to serious complications, including pelvic inflammatory disease, infertility, or spread to other parts of the body. Early treatment prevents these risks.
A positive result means you likely have gonorrhea and should follow your provider’s treatment plan immediately. A negative result means the bacteria were not detected in this sample, but STIs can sometimes be missed or may require testing for other pathogens.
How long does it take to get results?
Results are typically available within 2–5 business days, depending on lab processing times. Your healthcare provider will contact you once results are ready.
What if I have no symptoms but test positive?
Even without symptoms, gonorrhea can still be present. Treatment is essential to prevent complications and to protect others from infection. Your provider will prescribe antibiotics tailored to the bacteria found.
