What This Test Measures

The test detects viral RNA using a specialized probe that binds to genetic material from certain viruses. If the probe finds viral sequences, it confirms the presence of the virus in your vaginal sample.

Why It’s Ordered

Your healthcare provider may order this test if you have symptoms like unusual vaginal discharge, sores, or itching, or if you’re at risk for certain viral infections (e.g., sexually transmitted viruses). It’s also used during pregnancy to screen for high-risk viruses.

Sample Collection and Process

A healthcare professional collects a vaginal swab sample. The sample is then processed in a lab to extract viral RNA, which is analyzed using a sensitive probe-based method to detect viral genetic material.

What to Expect Before the Test

No special preparation is needed, but avoid douching or using vaginal products 24 hours before the test to ensure accurate results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance

Frequently asked questions

This test helps confirm or rule out viral infections that may require treatment or further monitoring. Early detection can guide treatment decisions and reduce transmission risk.
This test is qualitative, meaning it only tells whether viral RNA is present or not—not the exact amount or type of virus.
Will I need follow-up tests if this test is positive?
Yes, a positive result may prompt additional testing (e.g., culture or PCR) to identify the specific virus and determine the best treatment plan.
Can I take antibiotics if this test is positive?
No, antibiotics won’t help with viral infections. Your provider will recommend antiviral medications or other treatments based on the specific virus detected.
