    Advanced Functional Diagnostics

    Your Labs Were "Normal." But You're Not Well.

    Conventional labs are designed to rule out disease — not find dysfunction. Our advanced functional testing reveals what's actually happening at the cellular level — so we can build a protocol that actually works.

    Why "normal" lab ranges miss the dysfunction driving your symptoms.
    200+ biomarkers across every body system — not just 7 markers.
    At-home kits, optimal ranges, and a personalized root-cause protocol.

    The Core Problem

    Why Standard Labs Miss the Mark

    Conventional labs are calibrated to detect disease — not dysfunction. By the time your markers are "out of range," you've often been suffering for years.

    Advanced functional lab panels that reveal hidden dysfunction
    Clinical Reality

    "Normal" labs don't mean healthy

    Standard reference ranges are drawn from a sick population — dysfunction can hide inside "normal" for years.

    "Normal" Ranges Are Too Wide

    Lab reference ranges are based on the average of a sick population. Being in the bottom 2.5% of a diseased group is not the same as being healthy.

    Only 7 Markers Tested

    A standard metabolic panel checks 7–14 markers. A comprehensive functional workup analyzes 200+ biomarkers across every body system.

    Serum ≠ Cellular Levels

    Blood serum levels of nutrients like magnesium and B12 can appear normal while cells are severely depleted. We test what's actually inside your cells.

    No Functional Markers

    Standard labs never check organic acids, hormone metabolites, gut pathogens, or methylation — the markers that reveal how your body actually functions.

    Treated as Isolated Numbers

    A single lab value means nothing without context. Functional medicine interprets every marker in relation to your symptoms, history, and other results.

    Designed for Diagnosis, Not Prevention

    Conventional labs are designed to diagnose disease after it's already developed — not to identify the dysfunction that causes disease years before it appears.

    Our Approach

    Testing That Tells the Whole Story

    Every patient receives a personalized lab panel based on their symptoms, history, and health goals. We don't run the same panel on everyone — we run the right tests for you.

    Optimal Ranges, Not Just "Normal"

    Conventional labs flag you as normal if you're in the bottom 2.5% of a sick population. We use functional optimal ranges that reflect true health.

    Advanced Specialty Labs

    We partner with Genova Diagnostics, Cyrex Labs, Great Plains Laboratory, and Doctor's Data — the gold standard in functional testing.

    Interpreted in Context

    A lab value means nothing in isolation. We interpret every marker in the context of your symptoms, history, and the full clinical picture.

    Root-Cause Focused

    We're not looking for a diagnosis to match a drug. We're looking for the underlying dysfunction driving your symptoms — then correcting it.

    Advanced Testing Panels

    The Labs We Run — and Why

    Each panel is selected based on your specific symptoms and goals. Here's what we test and why it matters.

    Comprehensive Thyroid Panel

    Standard TSH alone misses 70% of thyroid dysfunction. Our full panel reveals conversion problems, autoimmune attacks, and cellular resistance.

    Tests Included

    • TSH
    • Free T3
    • Free T4
    • Reverse T3
    • TPO Antibodies
    • Thyroglobulin Antibodies
    HypothyroidismHashimoto'sWeight ResistanceBrain FogFatigue

    DUTCH Hormone Panel

    The gold standard in hormone testing. Dried urine captures hormone metabolites across a full day — far more accurate than a single blood draw.

    Tests Included

    • Estrogen Metabolites (E1, E2, E3)
    • Progesterone
    • DHEA-S
    • Cortisol Rhythm
    • Testosterone
    • Melatonin
    Hormonal ImbalancesAdrenal FatiguePMS/PMDDLow LibidoSleep Issues

    GI-MAP Stool Analysis

    DNA-based stool testing identifies pathogens, parasites, and microbiome imbalances that standard stool cultures completely miss.

    Tests Included

    • H. pylori
    • Parasites & Worms
    • Candida & Fungi
    • Zonulin (Leaky Gut)
    • Secretory IgA
    • Beneficial Bacteria Levels
    IBS/IBDLeaky GutCandida OvergrowthParasitesAutoimmune Disease

    Organic Acids Test (OAT)

    A single urine test that reveals metabolic dysfunction at the cellular level — showing how well your body produces energy, detoxifies, and makes brain chemicals.

    Tests Included

    • Mitochondrial Function Markers
    • Neurotransmitter Metabolites
    • Yeast & Bacterial Overgrowth
    • Oxalate Levels
    • Vitamin & Mineral Status
    • Detoxification Capacity
    Chronic FatigueADHDAutismAnxiety & DepressionFibromyalgia

    Food Sensitivity Testing (IgG/IgA)

    Unlike IgE allergy tests, this identifies delayed (24–72 hour) immune reactions that cause chronic inflammation, brain fog, and gut damage.

    Tests Included

    • 200+ Food Antigens
    • IgG Delayed Reactions
    • IgA Mucosal Reactions
    • Lectin Sensitivity
    • Gluten/Gliadin Antibodies
    • Cross-Reactive Foods
    Food SensitivitiesEczemaMigrainesBloatingAutoimmune Flares

    Advanced Metabolic Panel

    Standard cholesterol panels miss 50% of cardiovascular risk. We look at insulin resistance, inflammation, and lipoprotein particle size — the real predictors.

    Tests Included

    • Fasting Insulin & HOMA-IR
    • HbA1c & Fasting Glucose
    • NMR Lipoprofile (particle size)
    • Homocysteine
    • hs-CRP (inflammation)
    • Uric Acid
    Diabetes RiskCardiovascular DiseaseMetabolic SyndromeObesityPCOS

    MTHFR & Methylation Panel

    40% of the population carries MTHFR mutations affecting detox, neurotransmitters, and cardiovascular health. Standard labs never check this.

    Tests Included

    • MTHFR C677T & A1298C
    • Homocysteine
    • Folate (RBC)
    • B12 (Active)
    • SAM/SAH Ratio
    • CBS & COMT Variants
    MTHFR MutationDepressionMiscarriageBlood ClotsDetox Issues

    Heavy Metals & Toxin Panel

    Environmental toxins accumulate silently for years, disrupting hormones, neurological function, and immune regulation. Most doctors never test for them.

    Tests Included

    • Mercury, Lead, Arsenic, Cadmium
    • Aluminum & Nickel
    • Glyphosate (Roundup)
    • BPA & Phthalates
    • Mycotoxins (Mold Toxins)
    • Organophosphate Pesticides
    Mold ToxicityNeurological SymptomsHormone DisruptionAutoimmune DiseaseChronic Fatigue

    Micronutrient & Mineral Panel

    Serum levels of nutrients are often normal even when cells are depleted. Intracellular testing reveals the true nutritional status driving your symptoms.

    Tests Included

    • Intracellular Magnesium
    • Zinc & Copper Ratio
    • Vitamin D (25-OH)
    • Vitamin B12 & Folate
    • Iron Studies (Ferritin, TIBC)
    • Selenium & Iodine
