Functional Lab Testing

Real Data.  Real Results.

The purpose of running labs is not to diagnose conditions but to rather to find hidden points of stress in the body.  Through blood, urine, hair and stool testing we can gather data on patterns of imbalance and target our approach in a very individualized way.  One symptom or health struggle can be the result of many factors, and with testing, we can prioritize addressing the weak links in the body.

Hormone and Adrenal Function Testing


What has been referred to as adrenal fatigue is actually dysregulation of the HPA Axis. HPA Axis stands for the hypothalamic pituitary adrenal axis, and it’s the control center for your body’s stress response. Under stress, a cascade of hormone changes result in the production of cortisol. Although Cortisol is known as the stress hormone it has important benefits for our wellbeing such as helping to regulate blood sugar, metabolism and acting as an anti-inflammatory.  

My preferred hormone testing is done through the DUTCH (dried urine test for comprehensive hormones). It captures samples, spaced throughout the day to reflect the true circadian rhythm that your body is following. This test is a comprehensive assessment of sex and adrenal hormones and their metabolites.  It also includes the daily, free cortisol pattern, organic acids, melatonin


As we often operate in a constant state of stress, cortisol production can be out of balance.  Stressors that impact cortisol can include chronic illness, depression, surgery, high sugar intake and overconsumption of inflammatory foods, sleep deprivation, chronic or acute infections like H. Pylori or Candida.

This can lead to a downstream cascade of potential issues with thyroid, and sex hormone production.

Common Symptoms of HPA Axis Dysregulation:

  • Weight gain and/or inability to lose weight

  • Food and/or environmental allergens

  • Catching colds/viruses easily

  • Lightheadedness when moving from a seated or prone position to a standing position

  • Brain fog

  • Lack of energy

  • Fatigue or tiredness that won’t go away no matter how much sleep you get

  • Difficulty falling and/or staying asleep

  • Hypoglycemia

  • Frequent nighttime urination

  • Craving for salty and/or fatty foods

  • Lack of stamina to workout

  • Atypical exhaustion from a workout

  • Diminished sex drive

GI-Map Testing

The GI-Map is a single sample stool test that that measures gastrointestinal microbiota DNA.  This test will detect microbes that may be disturbing normal microbial balance or contributing to illness as well as indicators of digestion, absorption, inflammation, and immune function.

Chronic infections deplete your body’s ability to produce regenerative hormones, like DHEA, testosterone, progesterone, thyroid hormone, and growth hormone. Infections will also take a toll on our adrenal health causing an HPA axis dysregulation further worsening how one feels.

Reported on the GI-Map:

  • Bacterial, parasitic and viral pathogens

  • Normal / commensal bacteria levels

  • Opportunistic microbes

  • Parasites

  • Intestinal markers for digestions, inflammation and immune response

Indications for Testing: 


  • Brain fog

  • Sugar cravings

  • Mood disturbances (anxiety or depression)

  • Skin issues

  • Nutrient deficiencies (anemia)

  • Allergies

  • Fatigue

  • Bloating

  • Gas

  • Indigestion

  • Diarrhea

  • Constipation

  • GERD or acid reflux

  • IBS

  • Crohn’s Disease

  • Ulcerative colitis

Hair Tissue Mineral Analysis (HTMA)

Minerals are known as the "spark plugs" of the body and are needed for almost every enzymatic reaction.  The levels of the minerals and their ratios need to be balanced for optimal cellular function. 

The hair is one of the places the body eliminates minerals and heavy metals and can be tested to give insight into body chemistry and health conditions. 

The HTMA  gives insight into:

  • Heavy Metal Toxicity

  • Mineral Deficiencies and Imbalances

  • Metabolic Rate (fast or slow)

  • Adrenal Fatigue

  • Thyroid Function

  • Nervous System Imbalances

  • Protein Synthesis

  • Inflammation

  • Energy Levels

  • Mental Health Issues

  • Liver & Kidney Stress

  • Carbohydrate Tolerance & Blood Sugar Imbalances like Diabetes and Insulin resistance

Mediator Release Testing (Food Sensitivities)

There are 3 categories of diet-induced inflammatory reactions: Food Allergy, Food-Induced Autoimmune Disease, and Food Sensitivities. Of the 3, food sensitivities are the most prevalent.

Food and food-chemical sensitivities one of the most important sources of inflammation and symptoms across a wide range of chronic inflammatory conditions. They are also one of the most clinically challenging.

Food and food-chemical sensitivities have clinical characteristics that make it very challenging to identify trigger foods. For example, symptom manifestation may be delayed by many hours after ingestion; reactions may be dose dependent; because of a breakdown of oral tolerance mechanisms, there are often many reactive foods and food-chemicals; even so-called anti-inflammatory foods, such as salmon, parsley, turmeric, ginger, blueberry, and any “healthy” food can be reactive.

Conditions where food sensitivities can play a primary or secondary role:

  • Irritable Bowel Syndrome

  • Functional Diarrhea

  • GERD

  • Crohn’s Disease

  • Ulcerative Colitis

  • Microscopic Colitis

  • Cyclic Vomiting Syndrome

  • Migraine


  • Autism Spectrum Disorders

  • Epilepsy

  • Depression

  • Insomnia

  • Restless Leg Syndrome

  • Figromyalgia

  • Inflammatory Arthritis

  • Atopic Dermatitis

  • Urticaria

  • Psoriasis

  • Chronic Fatigue Syndrome
