Advanced Functional Medicine Diagnostic Testing
At Foundational Health, we specialize in getting answers where others stop asking questions. Many patients in Jacksonville and Jacksonville Beach, FL, come to us after being told their labs are “normal”—yet they still feel unwell. Our advanced functional medicine diagnostic testing digs deeper to uncover imbalances, dysfunctions, and root causes that traditional labs often miss. Whether you’re dealing with fatigue, gut issues, autoimmunity, or brain fog, the right tests provide the foundation for targeted, effective healing.
What Makes Functional Medicine Testing Different?
Unlike standard lab work that screens for disease markers within broad reference ranges, functional medicine testing focuses on optimal ranges and how systems in your body function together. These tests help uncover early dysfunction before it becomes disease. They often evaluate:
-
Hormone imbalances
-
Nutrient deficiencies
-
Gut microbiome health
-
Toxin and heavy metal exposure
-
Immune function and autoimmunity
-
Mold and chemical sensitivity markers
-
Inflammatory and metabolic markers
Our Process: What to Expect
We begin with a Discovery Call and Initial Consultation to determine which tests are appropriate based on your symptoms and history. From there, we may use a combination of:
-
Blood, saliva, stool, or urine testing
-
At-home kits or in-clinic draws
-
Specialty labs including mold, mycotoxins, food sensitivities, organic acids, and more
After your results come in, we provide a full Case Review and create a personalized care plan that fits your goals and lifestyle.
3 Key Benefits of Advanced Testing
Deeper Insight into Your Health
Standard labs often miss the nuances of chronic illness. Our advanced panels provide a clearer picture of what’s happening beneath the surface, so we can identify subtle dysfunctions before they escalate.
Personalized Treatment Plans
With the right data, we can tailor your care based on your unique biology—targeting the why, not just the what. Testing helps us create a protocol that’s as individualized as you are.
Save Time and Frustration
Many patients waste years trying to figure out what’s wrong. Comprehensive testing provides clarity and direction, so you can stop guessing and start healing with confidence.
“I was struggling with Hashimoto’s and could barely get through my day. Foundational Health helped me understand the root of my immune issues and gave me a plan that actually works. I finally feel like myself again.”
“For years, I bounced between doctors with no real answers for my autoimmune joint pain. The team here listened, tested, and gave me a step-by-step approach that’s changed everything.”
“I had Lupus and chronic fatigue that left me hopeless. Dr. Jackson’s team helped me rebuild my immune system and my confidence. Their approach is unlike anything else.”
Frequent Asked Questions
How are these tests different from what my primary care doctor orders?
Most conventional labs look for disease states using broad reference ranges. We look at optimal function and early dysfunction. This allows us to address problems at their root, often long before they show up on standard labs.
Are these tests covered by insurance?
Typically, advanced functional lab testing is not covered by insurance. However, we work with transparent pricing and offer a range of options to suit your needs and budget.
How much do these labs cost?
Prices vary depending on the type and number of tests. Some start as low as a few hundred dollars, while more comprehensive panels can be $1,000 or more. We’ll guide you to the right level of testing for your case.
How long does it take to get results?
Most labs return results within 2–3 weeks. After that, we schedule a Case Review session to explain your results and map out your care plan.
Do I need to come into the office for testing?
Not always! Many of our test kits can be completed from home and mailed in. For certain panels, a local blood draw may be required.
