Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like painful urination, discharge, or pelvic pain, or if you’ve been exposed to gonorrhea. It’s also used in screening for sexually active individuals at higher risk.

How the Test Works

The test detects gonorrhea bacteria in your urine using a sensitive immunoassay method. A small urine sample is tested for specific bacterial antigens, which the test identifies with high accuracy.

What to Expect Before the Test

No special preparation is needed. You’ll provide a urine sample, typically collected in a sterile container. Avoid urinating for about an hour before testing if instructed, but this isn’t always required.

What to Expect During the Test

The test is quick and painless. A healthcare provider or lab technician will collect your urine sample, and results are often available within hours or the next day.
