Comprehensive Functional Lab Testing for Real Answers
At The Facility Denver, we specialize in advanced functional testing to help uncover the underlying causes of your health issues. When symptoms don't make sense and "normal" labs come back, it's time to look deeper. We use clinical and functional testing to uncover what routine screenings often miss: gut dysfunction, hormonal imbalance, metabolic concerns, nutrient deficiencies, mold exposure, toxic burden, and more.
These tests aren't about collecting data. They're about changing direction.
Our Approach to Labs
Labs only matter if they change what happens next.
We don't run every test on every person. We test with intention. Each panel is chosen to explain why the body is reacting, not just label what it's doing. The goal isn't more information. It's clarity, so treatment becomes obvious.
This is root-cause healthcare, not recreational testing. When the right data meets the right plan, things finally shift.
Types of Labs We Use
Functional Medicine isn't about guessing. It's about measuring what matters. Below are some of the core lab categories we use to uncover the "why" behind your symptoms. Each panel offers a different window into how your body's systems communicate (or misfire).
Baseline Biomarker Panel
The Baseline Biomarker Testing is a comprehensive blood test, analyzing over 100 total biomarkers.
This test encompasses multiple organ systems analysis, to help us evaluate your baseline health status. This is the standard panel for all new patients. We recommend this panel annually.
Gut & Microbiome Testing
Your gut isn’t just about digestion — it’s your immune system’s control center.
We use comprehensive stool and microbiome panels (like the Gut Zoomer) to identify bacterial imbalances, pathogens, and inflammatory markers that affect everything from mood to metabolism.
Metabolic & Cardiovascular Health
Standard lab markers like glucose, insulin, and cholesterol all show metabolic function.
Advanced panels (like our Core+ or Healthspan labs) go beyond routine bloodwork, measuring ApoB, insulin resistance, and nutrient status to catch early dysfunction long before disease develops.
Hormones & Adrenal Panels
Fatigue, sleep disruption, irregular cycles, mood swings — these all trace back to hormone signaling.
Panels like DUTCH or HormoneZoomer show how your hormones behave over the course of the day, not just at one static moment. This helps us see stress patterns and recovery capacity.
Mold & Environmental Toxins
When exposure goes unnoticed, toxins can quietly drive fatigue, brain fog, and inflammation.
Mycotoxin panels and environmental screens reveal what your body is carrying — and guide strategies to help it release what’s weighing it down.
Autoimmune & Immune Function
Autoimmunity doesn't happen overnight. It builds for years before a diagnosis.
Immune-focused panels help us see early reactivity patterns, antibody production, and food/environmental triggers that keep inflammation simmering under the surface.
All of these labs are available through The Facility...the difference lies in how you access them.
Whether you’re working directly with our team or ordering your own panels, the process begins the same way: with curiosity and data.
FOR PATIENTS
Labs Within Personalized Care
Best for: Those who want a full evaluation, treatment plan, and ongoing guidance.
When labs are part of your care, they’re ordered after your provider understands your history, symptoms, and goals. We interpret your results in detail, build a treatment plan around them, and follow through on the changes they reveal. Some provider-only tests — such as DUTCH and MARCoNS — are only available through this route.
FOR SELF-STARTERS
Direct Order Labs
Best for: Those who want data first and decisions later.
Our Direct Order Lab Shop offers access to many of the same panels we use in our clinic — without becoming a patient. You select the tests, receive your kit, and get your results through a secure portal. Interpretation sessions are optional and available as an add-on if you’d like clinical context once your results arrive.
