Genova Diagnostics
Provides advanced stool and nutrient testing to identify imbalances like bacterial overgrowth (SIBO), Candida, parasites, leaky gut, and food sensitivities. These labs are ideal for uncovering hidden causes of bloating, digestive issues, and autoimmune flare-ups.
Gut health pioneers—stool testing for dysbiosis (GI Effects), food sensitivities (FMV), and metabolic pathways (NutrEval).
Best For:
IBS/SIBO patients
Unexplained bloating
Autoimmune triggers
Bacteria & parasites & Candida
Leaky gut syndrome
Dutch Hormone Lab
Uses dried urine testing to map cortisol patterns, estrogen metabolism, and adrenal health. Ideal for identifying the root causes of perimenopause symptoms, PCOS, weight gain, mood changes, and male hormone imbalances.
This test provides a comprehensive view of hormone production, detox pathways, and daily rhythms—something traditional blood tests often miss. It’s especially useful for uncovering hidden stress patterns, hormonal imbalances, and how your body processes key hormones.
The gold standard for hormone mapping—cortisol rhythms, estrogen metabolites, and adrenal fatigue patterns (via dried urine).
Best For:
Perimenopause/menopause
PCOS
Unexplained weight gain
Male hormones
Cortisol patterns

Frequently Asked Questions
Your Testing Questions Answered
How is this different from my doctor’s lab work?
Conventional labs look for disease. My tests uncover dysfunction—hidden imbalances in hormones, gut health, toxins, or epigenetics that explain why you feel "off" long before disease appears.
Will insurance cover these tests?
Some tests (like Quest) may be covered; others (like TruDiagnostics or DUTCH) are self-pay. I prioritize tests with the highest clinical value—think of them as an investment in catching problems early, when they’re easiest to reverse.
How do I know which test(s) I need?
That’s where my expertise comes in. In our consultation, I’ll listen to your symptoms and goals, then recommend the exact tests to uncover your root causes—no guesswork.
What happens after I get my results?
You’ll get a detailed interpretation (not just a lab report) and a customized plan—whether it’s fixing gut imbalances, optimizing hormones, or reducing cancer risk.
Are these tests accurate?
I only use FDA-approved or CLIA-certified labs with peer-reviewed science behind them (like TruDiagnostics’ aging research or GRAIL’s cancer detection). No "junk science" here.
Can’t I just order these myself?
You could—but without a functional medicine expert to interpret them, you’re left with raw data and Dr. Google. I connect the dots between your results, symptoms, and personalized solutions.
