This test measures the levels of important hormones and related substances in your body. Hormones act as chemical messengers that help regulate metabolism, energy, mood, sleep, and reproductive health. By measuring these levels, your healthcare provider can determine whether they fall within a normal, healthy range for you.
The test detects specific bacterial DNA sequences present in vaginal fluids. It identifies common bacteria like Lactobacillus (which supports health) and potential pathogens (like *Candida* or *Gardnerella*). The probe method allows for a broad overview of microbial diversity without measuring exact concentrations.
Your provider may order this test if you have symptoms such as unusual fatigue, unexplained weight changes, mood swings, sleep disturbances, irregular periods, or changes in appetite. It can also be used to monitor an existing condition, investigate possible hormonal imbalance, or check how well a current treatment is working.
A vaginal microbiome test may be recommended if you experience recurrent vaginal infections, unusual discharge, itching, or discomfort. It can also help diagnose conditions like bacterial vaginosis or yeast infections by assessing microbial balance.
The sample is usually collected through a simple blood draw. A trained technician will clean the skin on your arm, wrap a band around your upper arm, and collect a small amount of blood from a vein into a sealed tube. The procedure takes only a few minutes, and most people can return to their normal activities right away.
A healthcare provider will collect a sample from your vagina using a sterile swab or probe. The sample is then analyzed in a lab to identify bacterial DNA patterns.
Common findings include hormone levels that fall within the expected range, or results that come back higher or lower than normal. An abnormal result may suggest a hormonal imbalance, thyroid dysfunction, chronic stress, or another underlying condition. Your provider will interpret your results together with your symptoms and medical history before recommending next steps.
Typically, a healthy vaginal microbiome is dominated by *Lactobacillus* species, which help maintain acidity and prevent harmful bacteria. Abnormal findings might include reduced *Lactobacillus* levels or the presence of unusual bacteria, which could indicate an imbalance.

Frequently asked questions
This test helps diagnose and monitor conditions like bacterial vaginosis, yeast infections, or other microbial imbalances that may not be detected by traditional cultures. Early identification can guide targeted treatment and prevent complications such as pelvic inflammatory disease or preterm labor.
Results are usually available within 3–7 business days, depending on lab processing times. Your healthcare provider will discuss the findings with you during your follow-up visit.
If your test shows an imbalance, your doctor may recommend probiotics, antifungal medications, or antibiotics tailored to the specific bacteria identified. Lifestyle changes, such as avoiding douching or certain hygiene products, may also help restore balance.
