What is Functional Medicine?

FM is an individualized approach to identifying the root causes of disease that are based on nutritional science, genomics, and epigenetics. Once identifying them, a protocol using natural agents is used. Nutraceuticals, herbal medicine, stress management, supplements, lifestyle changes, and detoxification plans all can be used to help restore function and health.

Functional Medicine can help those with chronic health issues, autoimmune diseases, thyroid disease, hormonal imbalances, digestive issues and much more. It uses the power of science, nature and medicine to get to the root cause.

Why Standard Labs Aren't Enough

Why are my blood tests normal
…but I don’t feel normal?

Sometimes standard tests are not enough. Testing is a key way to understand one’s disease process. Innovative tests can be very valuable in identifying undetected causes of ailments. Functional Medicine is when you use these tests to understand the biochemistry behind a disease process and then apply the corresponding care to correct the imbalances.

In Functional Medicine, we also work in functional ranges versus regular laboratory ranges. This range is smaller and is where that marker is optimal. If you are normal-lab-low or normal-lab-high, this is a gray area where you may not be fully diseased or diagnosable, but you are beginning to experience symptoms. FM recognizes these gray areas and starts to address them before they become diseased.

We run the following seven categories of testing — not on every patient, but whichever are indicated by your history and presentation.

Advanced Testing

Discover hidden health issues with advanced testing.

Every panel below includes the results-review consultation with Dr. Nazzar — the findings, the plan, and your next steps, walked through together.

Comprehensive Intestinal

Comprehensive Intestinal Testing

$805

Optimize gut health for total wellness.

  • The gut microbiome influences digestion, immunity, metabolism, and brain function.
  • This test uncovers inflammation, bacterial imbalances, parasites, and “leaky gut” (intestinal permeability).
  • Find out how your gut health may be triggering chronic illness.

Overwhelmingly, research indicates that gut health impacts overall health. The gut microbiome, in particular, plays a critical role in mediating the effects of diet and other factors on health — including digestive, immune, metabolic, and neuroendocrine functions.

This test also checks how you digest fats and carbohydrates; it checks for inflammation, good bacteria levels, yeast (Candida), bacteria, parasites, and for intestinal permeability — also known as leaky gut. Assessing GI health with the proper tools can help get to the root cause of chronic illness.

Test details Stool · 2–3 weeks
Organic Acids

Organic Acid Testing — “OAT”

$655

Uncover imbalances impacting brain and energy levels.

  • Identifies neurotransmitter issues affecting mood, focus, and brain function.
  • Detects energy production deficits (mitochondrial function) and nutrient deficiencies.
  • Ideal for: fatigue, ADHD, digestive problems, muscle pain, and headaches.

This testing is a comprehensive evaluation that detects mitochondrial deficits which can attribute to many chronic ailments. It checks for neurotransmitters that affect mood and brain health. It checks for nutritional and antioxidant biomarkers, fat metabolism, methylation issues, fungal and bacterial infections, oxalates, and other markers that play a key role in inflammation, immune health, neurological development, and overall health.

This is great for patients with fatigue, autism, mood, focus and concentration issues, joint and muscle pain, headaches, and digestive issues.

Test details Urine · 2–3 weeks
Nutrients

Nutritional Testing

$899

Personalize your nutrition for optimal health.

  • Evaluates 125+ biomarkers to assess your need for vitamins, minerals, and antioxidants.
  • Identifies heavy metal exposure and oxidative stress.
  • Tailors supplement recommendations based on your body’s unique needs.

The NutrEval FMV®is both a blood and urine test that evaluates over 125 biomarkers and assesses the body’s functional need for 40 antioxidants, vitamins, minerals, omegas, amino acids, digestive support, and other select nutrients. This test also checks for heavy metals like mercury, oxidative stress, and toxic exposures.

Personalized recommendations for nutrients are determined by using an algorithm based on the patient’s test findings. This test will help tailor your supplements and diet according to nutrient needs.

Test details Blood + Urine · 2–3 weeks
Tox Detect

Tox Detect — Environmental Chemicals

$607

Detox your body from hidden environmental toxins.

  • Surfaces glyphosate, phthalates, parabens, BPA, and other plasticizers from urine.
  • Pinpoints exposure from packaged foods, household products, pesticides, and pollution.
  • Informs targeted detox pathways and binder protocols.

Every day, we are exposed to hundreds of toxic chemicals through products like pharmaceuticals, pesticides, packaged foods, household products, and environmental pollution.

As we have become more exposed to products and to toxic chemicals, we have been confronted with an accelerating rate of chronic illnesses like cancer, heart disease, chronic fatigue syndrome, chemical sensitivity, autism spectrum disorders, ADD, autoimmune disorders, mood disorders, Parkinson’s disease, and Alzheimer’s disease.

It is key to identify these chemicals that can be taxing your health so that you can target the proper detoxification pathway to properly eliminate them.

Test details Urine · 2–3 weeks
Trace Elements

Trace Elements — Hair Heavy Metals

$550

Map heavy-metal burden through hair analysis.

  • Non-invasive hair sample reveals long-term heavy-metal accumulation.
  • Reads mercury, lead, arsenic, cadmium, and aluminum alongside essential minerals.
  • Pairs naturally with Tox Detect for a full toxic-load picture.

Heavy metals build up over months and years — long after a urine snapshot would catch them. A hair sample looks at the longer exposure window and reveals the chronic burden driving fatigue, neurologic symptoms, autoimmunity, and developmental concerns.

The same hair sample also reads essential minerals like zinc, magnesium, selenium, and calcium — so we can correct the mineral imbalances that often come with heavy-metal toxicity.

Test details Hair · 2–3 weeks
EnviroTox Bundle

EnviroTox — OAT + Tox Detect Bundle

$1,032Bundle: OAT + Tox Detect

Pair metabolic insight with environmental-toxin screening.

  • Bundles two of our most-ordered urine panels for a single collection.
  • OAT reads mitochondrial, neurotransmitter, methylation, and fungal/bacterial markers.
  • Tox Detect surfaces glyphosate, phthalates, parabens, BPA, and other plasticizers.

When chronic symptoms could be either a metabolic issue, an exposure issue, or both, the EnviroTox bundle gives us the full picture from one collection. The Organic Acid Test shows where your metabolism, brain chemistry, and methylation are running off; Tox Detect shows the environmental chemicals quietly tipping them over.

Bundling the two saves you the cost of ordering separately and shortens the diagnostic window — one kit, one collection, one results review.

Test details Urine (single collection) · 2–3 weeks
EnviroTox Complete

EnviroTox Complete — MycoTox + Tox Detect + OAT

$1,250Bundle: MycoTox + Tox Detect + OAT

The full environmental-and-metabolic workup, in one collection.

  • Our most complete environmental workup — three panels, one urine collection.
  • Adds MycoTox to surface mold and mycotoxin exposures from buildings, vehicles, and foods.
  • Best when symptoms are chronic, hard to explain, and toxic load is suspected.

When you suspect mold on top of environmental chemicals and metabolic disruption, EnviroTox Complete is the workup we reach for. It combines the MycoTox profile, Tox Detect, and the Organic Acid Test into a single collection so we can see how mycotoxins, plasticizers, and metabolism are interacting in your body.

This is the panel we order for stubborn fatigue, brain fog, autoimmune flares, and recurrent sinus or respiratory symptoms when standard labs aren’t telling the whole story.

Test details Urine (single collection) · 2–3 weeks
Adrenals

Adrenal Testing

$690

Manage stress and restore energy levels.

  • Evaluates cortisol production to identify stress-related imbalances.
  • Symptoms like fatigue, insomnia, weight gain, and anxiety can indicate adrenal dysfunction.
  • Helps optimize sleep, immunity, and metabolism through targeted therapies.

The adrenal glands are in charge of producing the stress hormone cortisol. If cortisol is under- or overproduced, or even produced at the wrong times, it may lead to a variety of symptoms — stress, fatigue, insomnia, low immunity, hormonal imbalance, slower metabolism, and even blood sugar issues like diabetes.

This is how stress impacts our bodies and causes disease. Testing the adrenals is key to improve your sleep, immune, hormones, and overall health.

Test details Dried urine (4-point) · 2–3 weeks
Mold & Mycotoxins

Mold and Mycotoxins

$640

Identify mold exposure behind chronic symptoms.

  • Mycotoxins from mold can cause fatigue, brain fog, respiratory issues, and depression.
  • This test reveals hidden mold exposure and helps develop detox strategies.

Mycotoxins (toxins from mold) are some of the most prevalent toxins in the environment. Mycotoxins are metabolites produced by fungi like mold, which can infest buildings, vehicles, and foods. Mold can grow and colonize on almost any surface. They then release mycotoxins into the body causing symptoms of many different chronic diseases.

With the MycoTOX Profile, we can identify mycotoxin exposures and make recommendations for detoxification treatments that have been effective.

Test details Urine · 2–3 weeks
Food Sensitivity

Food Sensitivity Testing

Call for pricing

Eat right to reduce inflammation.

  • Identifies foods triggering gas, bloating, headaches, or brain fog.
  • Detects immune responses that happen hours after eating certain foods.
  • Helps personalize your diet to improve digestion and reduce inflammation.

Eating the correct foods is fundamental to overall health. Food sensitivity is a different immune response to food compared to a food allergy. Food sensitivities can cause immune responses and inflammation from 2–72 hours after exposure to the food.

This can make it difficult to identify what foods are causing gas, bloating, brain fog, headaches, arthritis, autoimmunity, inflammation, and other symptoms. This test will help identify exactly what foods you should and should not be eating.
