Genital Chlamydia trachomatis and Neisseria gonorrhoeae nucleic acid test (NAAT) by probe-based amplification
This test detects the genetic material of two sexually transmitted infections (STIs) that commonly affect the genital area, helping identify infections that may require treatment.
["A simple test to check for common STIs that can be spread during sex or skin-to-skin contact."]

Why This Test Is Done
Your healthcare provider may recommend this test if you have symptoms like unusual discharge, pain during urination, or sores, or if you are sexually active and at risk for STIs. It’s also part of routine screening for certain groups, such as sexually active young adults or those with multiple partners.
What to Expect During the Test
The test involves collecting a sample from your genital area using a small swab. This sample is then analyzed in a lab to detect genetic material from *Chlamydia* or *Neisseria gonorrhoeae*. The process is quick and usually painless.
What the Results Mean
If the test is positive, it confirms an infection with one or both bacteria. Treatment typically involves antibiotics, and follow-up may be needed to ensure the infection is fully cleared. If negative, you do not currently have an infection, but you should still practice safe sex and discuss prevention strategies with your provider.
Preparing for the Test
No special preparation is needed. You may shower or clean the genital area before the test, but avoid using soaps, perfumes, or douches that day, as they could interfere with the sample collection.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Both *Chlamydia* and *Neisseria gonorrhoeae* are bacterial infections that can cause serious health issues if untreated, such as pelvic inflammatory disease, infertility, or complications during pregnancy. Early detection and treatment are crucial to prevent these complications and reduce the risk of spreading infections to others.
