Functional Lab Testing in St. Louis
Real healing starts with the right data.
We combine focused blood work with biofeedback testing to uncover why you feel the way you do — and what you need to heal.

Clarity Before Protocols
We Only Measure What Matters
Most lab work looks for disease. Ours looks for patterns, revealing which systems are stressed and where to focus first.
Data is good.
The right data is better.

How it Works
Lab Testing in Our Process
Labs matter, but they don’t tell the full story.
This is why we combine labs with biofeedback testing to create a truly personalized plan for healing.
01
Test
You’ll receive your lab order by email and schedule your blood draw at the nearest LabCorp. Results in 3-5 days.
02
Interpret
We review your markers through functional ranges to reveal patterns and stress points standard labs often miss.
03
Integrate
Your lab findings are then combined with Systems Health Care (SHC) and fascia assessment to pinpoint exactly where your body needs support first.
04
Reassess
As you improve, we refine your plan and re-test labs every 3-6 months to track your progress and keep you moving forward.

Lab Testing FAQ
How is your approach different from other functional medicine clinics?
Many functional medicine clinics rely heavily on large, expensive test bundles. Our approach is more focused. We use a targeted Essentials Panel combined with SHC biofeedback to identify what your body needs without over-testing or overwhelm. This reduces costs, removes confusion, and helps you see results faster.
Do you take insurance?
We don’t bill insurance directly. This allows us to spend more time addressing root causes instead of following insurance restrictions. You’ll receive a superbill you can submit to your insurance for possible out-of-network reimbursement.
Can I use my HSA or FSA account?
Yes. Most patients use their Health Savings or Flexible Spending Accounts to cover visits, lab work, and supplements.
How much does the Essentials Lab Panel cost?
The Essentials Lab Panel is $250, and we offer it at cost to our patients as part of our services.
This keeps testing simple, affordable, and free of unnecessary panels or upsells.
Do I need to fast?
Yes — please fast 8–10 hours for accurate metabolic results.
Where are labs run?
We partner primarily with LabCorp for consistent, high-quality results.
If you need alternative lab options for accessibility or special circumstances, please contact us to discuss what’s possible.
Can I bring in recent labs from another provider?
Absolutely. We will integrate them to avoid unnecessary duplication and improve clarity.
Can I order more advanced testing?
Of course. After reviewing your Essentials Lab Panel, we may recommend additional testing if needed (e.g., hormones, gut, toxins). You can explore options though Fullscript or contact us for guidance. We always keep testing focused and purposeful — no unnecessary panels.
If you have specific labs you’re interested in, we’re happy to review them and decide together whether they’ll add value to your care.
