Functional Medicine Lab Testing

Advanced Lab Testing Services

Unlock precise answers with advanced testing designed to find and correct the root causes of chronic symptoms. Finding the key imbalances is especially important in complex cases like Hashimoto’s and autoimmune conditions. Each panel is selected to map the interactions between hormones, metabolism, gut health, nutrients, toxins, and immune function, so treatment plans are targeted and results are trackable.

Benefits of testing with us

Root-cause focus: go beyond “normal” ranges to identify patterns driving fatigue, brain fog, weight changes, digestive issues, and autoimmunity.

Whole-system view: connect thyroid, adrenal, gut, detox, and immune markers into one actionable plan instead of only addressing isolated systems.

Clear next steps: results translate into a personalized protocol and measurable milestones for long-term health maintenance.

How it works

Identify: begin with a comprehensive intake and a strategic test plan tailored to symptoms and history.

Personalize: review results in context, then design a step-by-step protocol with nutrition, supplementation, lifestyle, and follow-up labs.

Accountability: ongoing guidance to implement, refine, and sustain results with predictable progress.

Lab Test menu overview

Comprehensive blood testing

In-depth panels for thyroid, metabolic and cardiovascular risk, inflammation, nutrients, insulin resistance, autoimmunity screening, and more, with advanced lipid particle profiling as indicated.

Adrenal hormone profiles (DUTCH and saliva)

Evaluate cortisol rhythm, cortisol/cortisone metabolism, DHEA, and sex hormone metabolites to target stress, sleep, energy, and perimenopause/andropause patterns.

Organic Acids testing

Functional insights into mitochondrial energy, B-vitamin status, neurotransmitter metabolites, detox markers, yeast/bacterial byproducts, and oxalate balance.

Stool testing

Comprehensive microbiome mapping, pathogens, H. pylori, digestion and absorption, inflammation, immune markers, and gut barrier integrity to address IBS, SIBO-like symptoms, skin issues, and autoimmunity triggers.

Mycotoxin testing

Detect mold-related toxins and correlate with symptoms like fatigue, brain fog, sinus congestion, sensitivity, and autonomic dysregulation; integrate with environmental and detox strategies.

Toxic metals testing

Screen for mercury, lead, arsenic, and more with appropriate specimen types to inform safe, stepwise detoxification protocols.

Chemical exposure testing

Assess common environmental chemicals and metabolites to guide exposure reduction and liver support phases.

Biological age / longevity testing

Biological age, cellular health, and cardiometabolic risk metrics to guide longevity-focused nutrition, training, sleep, and targeted supplementation.

Genetic testing

Actionable SNP insights for detox, methylation, neurotransmitters, and nutrient needs; always interpreted in context with labs and symptoms.

What conditions most benefit from Functional Lab Testing?

Autoimmune and thyroid health: clarify triggers, reduce antibodies, and stabilize immune activity with targeted, data-driven interventions.

Persistent fatigue and brain fog: map adrenal rhythm, mitochondrial markers, nutrients, and toxins to restore energy and focus.

Gut and skin issues: identify dysbiosis, stealth infections, food-related immune activation, and barrier dysfunction for durable symptom relief.

What to expect

Easy scheduling and clear prep: guidance on fasting, timing, supplements, and at-home kit instructions for urine, stool, or saliva when applicable.

Local and remote testing options: in-person draws anywhere with Quest Diagnostics or Labcorp locations; many advanced tests use at-home kits with mail-in processing.

Transparent review: a collaborative results session that translates data into a clear plan with prioritized phases and follow-up timelines.

Getting started

Schedule a consultation to find out what lab tests might be right for you.

If already under care elsewhere, bring recent labs and we’ll fill the gaps with a targeted strategy.

Virtual care available: comprehensive testing and results reviews offered for local and out of state clients.
