At in2GREAT Functional Medicine, we believe that getting to the root cause of your health concerns starts with the right data. Symptoms can tell part of the story, but advanced, targeted lab testing reveals what’s actually happening beneath the surface.
We don’t settle for “normal” ranges. Through our trusted laboratory partners, we provide comprehensive, accurate, and highly targeted testing that allows Dr. Priest and the in2GREAT team to build a personalized, data-driven plan designed specifically for your body.
Why Functional Lab Testing Matters
Functional medicine labs go beyond basic screening by providing a deeper, more meaningful understanding of your health. Rather than waiting for disease to develop, these labs are designed to detect early dysfunction, identify root causes instead of just symptoms, and evaluate how different systems in your body interact. This approach allows us to gather actionable insights that guide truly personalized treatment plans.
Instead of simply asking, “Is something wrong?” we ask, “How well is your body actually functioning and what needs support?” Because when you understand your biology at a deeper level, you can finally make real, lasting progress.
Six Conditions We Target with Advanced Lab Testing
Many chronic and complex health conditions simply cannot be fully understood without detailed lab analysis. At in2GREAT, we frequently use functional labs to guide care for the following conditions. Of course, this list is not exhaustive. Talk to us about your unique situation.
Cancer does not develop overnight. It is often the result of long-term metabolic dysfunction, immune dysregulation, toxin exposure, and chronic inflammation.
Advanced lab testing can help evaluate…
- Immune system function
- Inflammatory markers
- Oxidative stress levels
- Nutrient deficiencies
- Metabolic health
This data allows us to take a metabolic and systems-based approach to cancer, helping create an internal environment that is less supportive of disease progression and more supportive of healing.
CIRS is often triggered by environmental exposures such as mold, biotoxins, or infections. It can lead to widespread inflammation and symptoms that affect nearly every system in the body.
Functional lab testing helps identify…
- Inflammatory markers tied to immune activation
- Toxin burden and detoxification capacity
- Genetic predispositions to impaired detox pathways
- Hormonal and neurological impacts
Without proper testing, CIRS is frequently overlooked or misdiagnosed. With the right data, we can begin to address it directly.
Digestive symptoms are often just the surface-level expression of deeper gut dysfunction.
Functional labs can assess the following areas:
- Microbiome balance
- Bacterial overgrowth or infections
- Intestinal permeability (leaky gut)
- Inflammation within the digestive tract
- Digestive enzyme function
By understanding what’s happening inside the gut, we can move beyond symptom management and work toward true digestive healing.
Thyroid dysfunction is one of the most commonly missed or misunderstood conditions in conventional medicine.
Many patients are told their thyroid is “normal” based on limited testing, but they still experience the following symptoms:
- Fatigue
- Weight gain
- Brain fog
- Hair thinning
- Hormonal imbalances
Functional lab testing gives us a complete picture of thyroid health (more on this below), allowing us to identify issues that standard labs often miss.
Brain health is deeply connected to inflammation, metabolism, circulation, and toxin exposure.
Advanced lab testing can evaluate…
- Markers of inflammation affecting the brain
- Blood sugar regulation and insulin resistance
- Nutrient deficiencies critical for cognitive function
- Toxin exposure
- Hormonal imbalances
This allows us to create a proactive plan to support memory, focus, and long-term cognitive resilience.
Weight loss is not simply about calories — it’s about biology.
Functional labs can uncover…
- Insulin resistance
- Hormonal imbalances (thyroid, cortisol, sex hormones)
- Inflammation
- Nutrient deficiencies
- Metabolic inefficiencies
When we understand what’s slowing your metabolism down, we can build a strategy that works with your body — not against it.
What Happens After Your Labs?
Lab testing is just the beginning. Once your results are in, Dr. Priest and the in2GREAT team perform a deep, comprehensive analysis that looks beyond isolated numbers.
We ask these questions:
- How are different systems in your body interacting?
- Where are the root imbalances?
- What patterns are contributing to your symptoms?
This is where functional medicine stands apart.
Your body is not a collection of isolated parts — it’s an interconnected system where each function influences the others. When we review your lab results, we often uncover imbalances across multiple areas, including immune function, hormones, gut health, detoxification pathways, mitochondrial (energy) function, and inflammation. These systems don’t operate independently, which is why addressing only one piece of the puzzle often leads to incomplete results.
Instead of treating each issue separately, we develop a personalized plan that considers how these systems interact and influence one another. By taking this comprehensive, systems-based approach, we can better support your body as a whole — because real healing happens when every system is working in alignment.
Based on your lab results, your care plan is tailored specifically to your needs and may include targeted nutrition strategies, supplement protocols designed to correct deficiencies, and lifestyle adjustments that support long-term health. We also focus on stress optimization, detoxification support, hormone balancing strategies, and gut restoration programs, depending on what your body requires.
In some cases, your plan may incorporate advanced therapies offered at in2GREAT, such as IV therapy for nutrient repletion and cellular support, oxygen-based therapies, red light therapy, and other regenerative or metabolic support treatments. Every recommendation is driven by your data, ensuring that your plan is precise, personalized, and built around helping your body function at its best — not based on a one-size-fits-all protocol.
Tracking Progress Through Retesting
Healing is a process, and progress should be measurable. That’s why we emphasize strategic retesting throughout your journey.
By evaluating your labs over time, we can…
- Confirm that your treatment plan is working
- Make adjustments when needed
- Identify new patterns as your body heals
- Provide objective evidence of your progress
Tracking progress is important when monitoring your path to greater health. By testing at various points throughout your personal treatment or optimization plan, we can further understand if what we’re implementing together is working, or if any adjustments need to be made.
Why Basic Lab Work Isn’t Enough
A common question we hear is “I already had labs done at my primary care office — why do I need more testing?”
The answer is simple: Most conventional lab panels are limited in scope and interpretation.
The Thyroid Example
In many traditional settings, thyroid evaluation may include only these:
- TSH
- T4
While these markers are helpful, they do not provide a complete picture of thyroid function.
At in2GREAT, we take a far more comprehensive approach by evaluating all of these markers:
- TSH
- T4 (total)
- T4 (free)
- T3 (total)
- T3 (free)
- Reverse T3
- T3 uptake
- Thyroid peroxidase antibodies (TPOAb)
- Thyroglobulin antibodies (TgAb)
Your Health, Backed by Data
When you have the right data, everything changes. You’re no longer guessing. You’re no longer chasing symptoms. You’re finally working with a clear, personalized plan.
At in2GREAT Functional Medicine, our goal is to give you…
- Clarity about what’s happening in your body
- Confidence in your treatment plan
- A path forward based on real, measurable insights
