The Standard Vaginal Test Looks for About 30 Microbes — Your Body Has Hundreds More
A single at-home swab reads 700+ bacteria and fungi, physician-reviewed in a certified lab, so recurring symptoms get a root cause instead of another round of guesswork.

ADVERTORIAL
Most gynecology offices use PCR or 16S sequencing. Both read a narrow band of microbes — the ones labs decided decades ago were worth looking for.
The problem: your vaginal microbiome contains hundreds of species of bacteria and fungi. The test your doctor orders reads maybe 30.
That gap is why infections keep returning. You get swabbed, the lab finds Candida or Gardnerella, you get the standard prescription.
Three months later, you're back. The infection never fully cleared, or a different microbe was driving it all along, or the antibiotic wiped out protective bacteria and made room for something worse.
A newer sequencing method — metagenomics — reads the whole ecosystem. Every microbe present, not just the ones PCR was designed to catch.
So, why can't a regular gynecology test catch all of this?
PCR matches DNA to a library of known sequences. If the lab has 30 microbes listed, it identifies those 30.
Everything else goes unmatched and unreported. 16S sequencing reads a narrow genetic marker that groups bacteria into families but often misses species-level detail and skips fungi entirely.
Metagenomics reads every fragment of microbial DNA in the sample—the actual genetic code—with no pre-selected list. The sequencing machine maps what's actually there, then matches it against a database of 700+ bacteria and fungi. The test doesn't guess which microbes to look for — it finds them all.
That's how recurring symptoms finally get a root cause. Lactobacillus levels too low to protect you. Ureaplasma that standard swabs missed. Gardnerella plus three other anaerobic species create a biofilm no single antibiotic can break. You see the full picture.
What does the Evvy test actually do differently?
Evvy is the only at-home vaginal health test that uses metagenomics sequencing. You swab at home, mail the kit back, and the sample goes to a CLIA/CAP/CLEP-certified lab — the same accreditation hospitals use.
A physician reviews every result before it's released.
The report names every microbe found. It shows which ones link to bacterial vaginosis, yeast overgrowth, aerobic vaginitis, or fertility concerns.
The lab cross-references your levels against peer-reviewed research — including a 2021 study that linked four microbiome markers to implantation success in IVF patients.
Results include a personalized treatment plan: evidence-based recommendations, lifestyle changes, and when relevant, a path to prescription treatment through Evvy's network of licensed providers.
You also get a free one-on-one session with a certified health coach who walks you through the findings. If you opt for the Expanded PCR Panel, the test adds detection for chlamydia, gonorrhea, trichomoniasis, Mycoplasma genitalium, and identifies antibiotic resistance patterns in 11 common microbes.

Why these details matter
1
Metagenomics detects 700+ microbes in one swab
Traditional vaginal tests use PCR or 16S sequencing, which identify only the microbes a lab is programmed to search for—missing rare species and novel pathogens. Evvy's metagenomics (mNGS) approach sequences the entire microbial community, uncovering bacteria and fungi that standard methods skip. One test replaces the fragmented multi-visit cycle that has historically left patients unsure why infections keep recurring.
2
Catches infections standard tests routinely miss
Patients with persistent BV, yeast, or UTI symptoms often test negative on conventional office tests, yet symptoms remain. Metagenomics catches microbes that standard PCR tests miss because it reads everything in the sample, not just a preset list—including atypical species like Gardnerella morphotypes and fastidious (slow-growing) organisms. For people cycling through treatments without diagnosis, this single test often ends the diagnostic dead end.
3
Physician-reviewed results with actionable treatment plan
Each result is reviewed by an OB-GYN and comes with a personalized treatment plan grounded in detected microbes and antibiotic sensitivities. The plan pairs evidence-based Rx options (when needed) with lifestyle and supplement recommendations. A free 1:1 health coach session ensures patients understand their results and can advocate for their care with their own provider.
4
Fertility outcomes linked to four microbiome markers
Patients pursuing pregnancy or IVF now have access to four microbiome markers (validated in Vitale et al. 2021) correlated with implantation rates and IVF success. This fertility-specific insight closes a gap in traditional gynecology, where microbiome status has been invisible. For those struggling with recurrent loss or failed transfers, understanding the microbial context shifts the conversation from "try again" to "here's why and how to optimize."
The Expanded PCR Panel identifies 10 antibiotic resistances across 11 common vaginal pathogens—which antibiotics will and won't work—so providers can prescribe with confidence instead of guessing. Rather than prescribe broad-spectrum antibiotics that may fail, providers can choose based on the exact sensitivities of a patient's microbes. For people who have already cycled through multiple failed treatments, this precision dramatically shortens the path to resolution.

Data Your Doctor Listens To
At your next OB-GYN visit, you bring your Evvy results (physician-reviewed, CLIA/CAP/CLEP certified) and antibiotic resistance breakdown if applicable; most doctors acknowledge they do not have access to this level of microbe resolution and adjust their approach based on your data.
Evvy uses metagenomics (mNGS) sequencing, which detects a broader range of microorganisms than traditional culture or PCR methods. Clinical validation is based on CLIA, CAP, and CLEP certification; results are not medical diagnoses. Treatment recommendations should be reviewed with a healthcare provider. Fertility insights are observational (Vitale et al 2021) and not guarantees of implantation or pregnancy outcomes.
How does it actually compare?
Standard gynecology testing uses PCR or 16S sequencing — methods designed to look for a short list of known microbes. Evvy reads the whole ecosystem. Here's what that difference looks like side by side.

Metagenomics technology vs. PCR or 16s (industry standard)
Yes — and it's often more comprehensive. Evvy uses the same lab standards hospitals do (CLIA/CAP/CLEP certification), and metagenomics has higher sensitivity than PCR. The test catches microbes traditional methods miss because it doesn't rely on a pre-selected list. Does my insurance cover this? Will I actually need Rx treatment, or is that an upsell? How much does the Expanded Panel cost?
Evvy screens for 700+ bacteria and fungi found in the vaginal and urinary microbiomes with one swab using metagenomics sequencing. Traditional tests at doctor's offices use limited PCR or 16s technology that only screens for a predefined list of microbes, missing many organisms Evvy detects.
Evvy uses metagenomics (mNGS) sequencing with improved analytical sensitivity and specificity—peer-reviewed and CLIA/CAP/CLEP validated—versus traditional PCR or 16s methods. This single comprehensive test identifies imbalances linked to BV, yeast, aerobic vaginitis, and recurrent UTIs that standard testing may miss.
Your $159 test includes physician-reviewed results, a personalized treatment plan with evidence-based next steps, and a free 1:1 health coach session. Prescription treatments are separate and vary by results, allowing you to explore options without hidden costs.
