Functional Diagnostics That Guide Personalized Care

Every test I recommend serves a purpose: to illuminate hidden imbalances and help us target treatment precisely. These insights allow us to uncover the true root causes rather than simply managing symptoms. With advanced testing options, you can gain clear answers about what’s really happening beneath the surface.

Hormone and Adrenal Testing
When hormones are out of balance, you feel it. My hormone testing assesses cortisol rhythms, thyroid function, and hormones to uncover the reasons behind fatigue, mood changes, or sleep disruption.

Screening Blood Panels 
These panels reveal patterns that routine labs often miss. These tests assess inflammation, nutrient status, thyroid function, and more, providing a detailed snapshot of your current health so we can move beyond symptom-chasing.

Comprehensive Stool and Digestive Analysis
Your gut tells a powerful story. Through stool testing, I evaluate digestion, microbiome balance, inflammation, and hidden infections - insights that often explain fatigue, food reactions, and immune challenges.

Environmental Exposure Testing (Mold, Heavy Metals, Pesticides, Chemicals, etc.) 
Environmental toxins can deeply impact energy, cognition, and immune health. I offer environmental exposure testing to identify mold, heavy metals, and chemical burdens that may be driving chronic symptoms and help you detoxify safely.

Food Intolerance Testing
Food sensitivities are a common but often missed trigger for inflammation and fatigue. Food intolerance testing identifies reactive foods so we can design a plan that supports digestion, energy, and healing from within.

Parasite Testing
Parasites can quietly affect digestion, mood, and energy. My tests for parasite infection detect both common and overlooked pathogens so we can restore balance and resilience from the inside out.

Chronic Infectious Disease Diagnostics
Some infections hide in plain sight. Through chronic infectious disease testing, we screen for pathogens and immune markers connected to long-standing fatigue, pain, or “mystery illness” giving us clarity to treat effectively.

Frequently Asked Questions

Do I need to be an existing patient to order lab testing?

Yes. Lab testing is available only for established patients. This ensures that your results are interpreted within the context of your complete health history, current symptoms, and ongoing care plan. A thorough understanding of your case allows for accurate analysis, appropriate test selection, and personalized treatment recommendations based on your results.

What makes functional lab testing different from standard testing?

Functional lab testing looks deeper than conventional panels. It helps identify early imbalances and root causes rather than only flagging disease. These tests often evaluate nutrient status, inflammation, hormones, digestion, and toxin exposure, providing a more complete picture of your health and how your systems work together.

How long does it take to get my results?

Turnaround times vary depending on the type of test, but most results are available within 2–4 weeks. Results are reviewed during your scheduled follow-up visit, where I’ll walk you through the findings and explain what they mean for your health in clear, actionable terms.
