If you’ve been struggling with chronic symptoms like fatigue, digestive issues, hormone imbalances, or unexplained weight changes, you’re not alone. Many people experience these frustrating health challenges without clear answers. That’s where Functional Lab Testing can make a real difference.

What Is Functional Lab Testing?
Unlike conventional lab tests that often focus on diagnosing diseases, functional nutrition lab testing digs deeper to uncover hidden imbalances and root causes of symptoms. These tests assess how well your body is functioning on multiple levels — including digestion, nutrient status, hormone balance, inflammation, and detoxification pathways.
As a Certified Functional Diagnostic Nutrition® Practitioner (FDN-P), I use these advanced lab tests to get a full picture of your health and create a personalized nutrition and lifestyle plan that targets your unique needs.
Why Choose Functional Lab Testing?
Identify Hidden Issues: Functional lab testing can reveal infections, food sensitivities, gut imbalances, hormone disruptions, and nutrient deficiencies that standard labs might miss.
Get Personalized Insights: Every body is unique. These tests provide data to tailor your diet, supplements, and lifestyle strategies specifically for you.
Prevent Disease Before It Starts: By identifying imbalances early, you can take steps to prevent chronic diseases and improve long-term health.
Track Progress Over Time: Functional testing helps monitor how your body responds to changes in your diet, lifestyle, and supplements.
Common Functional Lab Tests
Comprehensive Stool Analysis: Assesses gut bacteria, digestion, inflammation, and infections.
Food Sensitivity Testing: Identifies foods triggering immune reactions and inflammation.
Hormone Panels: Measures cortisol, estrogen, progesterone, and thyroid hormones to evaluate hormone balance.
Nutrient and Mineral Testing: Detects deficiencies in vitamins, minerals, and antioxidants.
Toxicity and Detoxification Profiles: Reveals how well your body is removing toxins and environmental stressors.
How Functional Lab Testing Guides Your Healing Journey?
When paired with your health history and symptoms, functional lab testing becomes a powerful tool. Instead of guessing what might be wrong, you get precise information to address the root causes—whether that’s healing your gut, balancing hormones, improving detoxification, or correcting nutrient gaps.
From there, you and your health coach can design a customized nutrition plan, targeted supplementation, and lifestyle adjustments that lead to lasting results.
