Comprehensive Lab Testing in Fort Mill, SC
“Test, Don’t Guess.”
Too many patients spend years trying to solve health challenges without the data they need to make meaningful progress. At Functional Health Center, we believe that real answers require real evidence — which is why comprehensive, advanced diagnostic testing is the foundation of everything we do.
During your medical consultation, we’ll determine which tests are most appropriate for your health history, symptoms, and goals. The results become the blueprint for your personalized treatment plan — ensuring that every intervention we recommend is grounded in your actual biology, not just a best guess.
Many of our test kits (urine, saliva, and stool collections) can be completed from the comfort of your own home. Those that require a blood draw can be completed at any Labcorp location nationwide. We provide detailed instructions for every test used throughout the course of your treatment.

Frequently Asked Questions About Lab Testing in
Why does Functional Health Center order different tests than my regular doctor?
Conventional lab panels are designed to identify pathology — disease that has already developed to a clinically significant threshold. Functional medicine testing is designed to identify dysfunction before it reaches that point, and to uncover patterns that standard ranges miss. We use functional reference ranges (what’s optimal, not just what’s not diseased) and test systems that most conventional labs simply don’t include, such as intestinal permeability, diurnal cortisol rhythm, organic acids, and comprehensive nutritional status.
Where do I go to get my lab work done?
Blood draws can be completed at any Labcorp location nationwide — no need to travel to our office. Stool, urine, and saliva collection kits are shipped directly to your home and completed at your own convenience. We provide clear, detailed instructions to guide you through every collection and submission step.
Will my insurance cover the lab tests?
Some tests may be eligible for partial reimbursement depending on your plan. We can provide superbills for patients who wish to submit claims to their insurance. However, because we operate outside the conventional insurance model, we select tests based on clinical need — not insurance coverage. Many of our most valuable panels are not covered by standard insurance plans.
How long does it take to get lab results?
Turnaround times vary by test type. Standard blood panels are typically available within a few days through Labcorp. Specialty panels — such as comprehensive stool analysis, organic acid testing, or mycotoxin panels — may take 2–4 weeks depending on the laboratory. Your provider will give you a specific timeline when ordering your tests.
What happens after I receive my lab results?
Your provider at Functional Health Center will schedule a dedicated review appointment to walk through your results in detail — explaining what each finding means, how the patterns connect, and what your personalized treatment plan will look like. This review is thorough; many patients tell us it’s the first time they’ve truly understood what’s happening in their body.
Can I request specific tests, or does my provider decide what to run?
Both. Your provider will recommend the panels most relevant to your health history and goals. But patients are always encouraged to share specific concerns or areas they want investigated. Your input matters in building the most useful and targeted diagnostic picture.
Does Functional Health Center test for mold toxicity and heavy metals?
Yes. We offer comprehensive mycotoxin and aflatoxin panels, as well as heavy metal and mercury toxicity testing. These are among the most commonly overlooked contributors to fatigue, brain fog, immune dysfunction, and hormonal disruption — and they’re rarely tested in conventional care.
