Why This Test Might Be Ordered

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

What to Expect Before the Test

No special preparation is needed. You’ll collect a midstream urine sample in a sterile container. If testing is done in a lab, you may be asked to provide a urine sample for analysis.

How the Test Works

The test detects specific proteins (antigens) from *Neisseria gonorrhoeae* bacteria using a rapid immunoassay method. Results are usually available within 15–60 minutes.

Test Limitations and Considerations

This test may not detect all cases of gonorrhea, especially if the infection is in the urethra, cervix, or rectum. False negatives can occur if the sample isn’t collected correctly or if the infection is very early or late-stage.

Clinical interpretation
