What This Test Measures

The test looks for genetic material from specific pathogens, including bacteria like *Chlamydia trachomatis* and *Neisseria gonorrhoeae*, as well as viruses such as *Trichomonas vaginalis* and *Human Papillomavirus (HPV)*. These are often responsible for vaginal infections that can cause symptoms like unusual discharge, odor, or discomfort.

How the Test Works

A small swab is gently inserted into your vagina to collect cells and fluids. The sample is then analyzed in a lab using a nucleic acid amplification technique to detect the presence of these pathogens.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms of a vaginal infection, have been exposed to certain sexually transmitted infections, or as part of routine screening, particularly if you are pregnant or have a history of recurrent infections.

Common Symptoms to Watch For

Symptoms may include unusual vaginal discharge (clear, white, green, yellow, or brown), odor, itching or burning in the vaginal area, pain during urination, or pelvic pain. However, some infections may not cause symptoms, so testing is crucial for early detection.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why is this test important?
Early identification of vaginal infections can prevent complications such as pelvic inflammatory disease, chronic pelvic pain, infertility, or increased risk of HIV transmission. Treating infections promptly can also help avoid spreading them to sexual partners.
How long does it take to get results?
Results are typically available within 1 to 3 business days. Your healthcare provider will discuss the findings with you during your follow-up visit.
What if I have no symptoms but my provider recommends this test?
Even without symptoms, routine screening can help detect infections early. This is especially important for pregnant women, those with multiple sexual partners, or individuals with a history of recurrent infections. Follow your provider’s advice for next steps based on the test results.
