How the Test Works

A small sample of saliva is collected from your mouth using a sterile swab. The sample is then analyzed in a lab to detect genetic material from *Neisseria gonorrhoeae*. This method is highly sensitive and can detect even small amounts of bacteria.

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like sore throat, redness, or pain in the throat, or if you’ve been exposed to gonorrhea. It’s also used in screening for sexually transmitted infections (STIs) in certain populations.

Preparation for the Test

No special preparation is needed. You may eat, drink, or brush your teeth before the test. Avoid rinsing your mouth with mouthwash, as it could interfere with the results.

What to Expect During the Test

The test is quick and painless. You’ll simply have a healthcare provider gently collect a saliva sample from your mouth. The sample is then sent to a lab for analysis, usually within hours or the next day.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Frequently asked questions

Gonorrhea is a bacterial infection that can cause serious health problems if untreated, including severe throat infections, spread to other parts of the body, or complications like arthritis. Early detection and treatment with antibiotics can prevent complications and spread to others.
This test helps confirm gonorrhea in the throat, allowing for prompt treatment to prevent complications. It’s particularly useful for people who may not have obvious symptoms or for those at higher risk of infection.
How long does it take to get results?
Results are typically available within 24 to 48 hours, depending on the lab’s processing time. Your healthcare provider will contact you once the results are ready.
Can I take antibiotics before the test?
No, do not take antibiotics before testing unless directed by your healthcare provider. Antibiotics can affect the test results and delay accurate diagnosis.
