What This Test Measures

The test uses a molecular probe to analyze RNA from vaginal cells. RNA can indicate the presence of certain bacteria, viruses, or inflammatory markers that may suggest infections like *Chlamydia*, *Gardnerella*, or other microbial activity. This is not a traditional blood or urine test but focuses on fluid from the vaginal area.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like unusual discharge, odor, itching, or if you’re at higher risk for sexually transmitted infections (STIs). It can also be part of routine screening for certain conditions in women of reproductive age.

Sample Collection and Process

A healthcare professional will collect a sample of vaginal fluid using a sterile swab. The sample is then processed in a lab to detect RNA sequences associated with specific pathogens or inflammatory responses. Results are qualitative (yes/no presence) or quantitative (relative amount) based on probe detection.

What the Results Mean

Results may show the presence or absence of targeted RNA sequences. A positive result suggests possible infection or inflammation, but further testing (e.g., cultures or additional molecular assays) may be needed for confirmation. Negative results do not rule out infection entirely if symptoms persist.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

This test is primarily used as a screening tool to identify potential vaginal infections early, which can prevent complications like pelvic inflammatory disease or chronic pelvic pain. Early detection allows for prompt treatment with antibiotics or other therapies tailored to the identified RNA profile.
This test is not a replacement for traditional diagnostic methods like bacterial cultures or PCR testing. Results should be interpreted by a healthcare provider in the context of your symptoms and medical history.
How long will I need to wait for results?
Results are typically available within 1–3 business days, depending on lab processing times. Your provider will contact you directly with findings.
Can I take anything specific before this test?
Avoid douching, sexual activity, or using vaginal medications 24–48 hours before the test to ensure accurate results. Follow any specific instructions provided by your healthcare provider.
