Lab Testing

Food Allergy & Sensitivity Testing

All panels are blood tests. IgG and IgA immune cells are markers for delayed food sensitivities, which can cause digestive problems (gas, bloating, constipation, diarrhea, heartburn/ GERD), joint pain, migraines, brain fog, skin rashes, acne, and more. IgE immune cells are markers for classic food allergies, which cause an immediate response of hives, scratchy throat, and anaphylaxis.

Cyrex Labs –An industry leader for IgA and IgG testing for wheat , gluten, gluten cross-reactions, plus an expanded panel measuring 180 foods (cooked and raw). Intestinal permeability (aka “Leaky Gut”) profile also offered.
Vibrant Wellness – IgA and IgG markers of 96 foods including nightshades, grains, proteins, fruits and vegetables. IgE food allergy testing also available.
Wheat Zoomer from Vibrant Wellness – Comprehensive panel looks at all the ways one can react to wheat and gluten, including wheat germ agglutinin. This test also includes a Leaky Gut profile.
Infinite Allergy Labs – IgE markers along with IgG4, which can block IgE. Measuring both helps determine the severity of the reaction. Plus IgG or delayed food sensitivity reactions with complement marker. This provides a comprehensive look at which foods cause inflammation.

Adrenal and Hormone Testing

DUTCH Adrenal – a urine test that measures total and free cortisol, DHEA and your body’s preference for cortisol versus cortisone. This helps to access adrenal function (the H-P-A axis) related to stress, weight gain, sleep, immunity, digestion and hormone balance.
DUTCH Complete – an expanded urine test including all of the components of the DUTCH Adrenal plus testosterone, progesterone, the 3 types of estrogen and how well your body is metabolizing and detoxifying estrogen. It also includes melatonin, markers for nutrient deficiency, oxidative stress, and neurotransmitter balance. DUTCH Complete is a comprehensive look at your hormone levels to learn the cause of irregular or difficult periods, PMS, insomnia, weight gain, acne, prostate issues and more.
DUTCH Plus – test includes all components of the DUTCH Complete with the addition of morning saliva cortisol markers for the Cortisol Awakening Response. This provides more information about your stress response.

Digestion – Stool and Breath Testing

Proper digestion and a well-balanced microbiome are crucial to optimal health. Not only does it affect digestion itself (gas, bloating, constipation, diarrhea, heartburn, abdominal pain) but it also affects mood through neurotransmitters; immune system through inflammation, autoimmunity and allergies; detoxification and hormones; plus skin, sleep and metabolism (weight management).

Stool tests

Both cultured and PCR-DNA stool tests are offered. Markers include: digestive function – fat and protein absorption; immune and inflammation; metabolic function and intestinal permeability – short chain fatty acids; microbiome – commensals (the good bugs); and pathogens (the bag bugs) including parasites, bacteria, yeast/ Candida, and H. Pylori.

GI Map by Diagnostics Solutions Laboratory – Quantitative PCR/DNA: measures digestive function, immunity, inflammation through commensals (the good bacteria) viruses, parasites, H.Pylori, and pathogens including virulence factors; option for zonulin (a marker for intestinal permeability, aka “leaky gut”).
GI Effects from Genova – Culture & PCR: measures digestive function, immunity, inflammation, pathogens and commensals (measured by PRC technology); option for zonulin (a marker for intestinal permeability, aka “leaky gut”); option for H. Pylori.

SIBO Breath Test

SIBO Breath Test, Genova Diagnostics – 3 hour lactulose challenge test measuring hydrogen and methane gases for Small Intestinal Bacterial Overgrowth. Interpretation includes analysis for hydrogen sulfide gas. Glucose challenge test available also.

Nutrients, Metabolism, Detox and Microbiome

Organix Comprehensive Profile by Genova – this urine test is of one of our favorites since it covers so many areas of health by measuring “organic acids.” According to Genova’s website, “Organic acids are metabolic intermediates that are produced in pathways of central energy production, detoxification, neurotransmitter breakdown, or intestinal microbial activity.” This test determines imbalances in metabolism and neurotransmitters (which influence depression, anxiety and other mood issues), nutrient deficiencies, antioxidant status, oxidative stress, detoxification function, and dysbiosis (the balance of good and bad bugs within your microbiome).

OMX Organic Metabalomics by Diagnostic Solutions Lab – Much like an emissions test measures how your car engine runs, OMX helps us understand how your body uses the foods you eat to support systems of health. OMX report includes: important nutrient markers for protein and vitamin status; metabolites related to imbalances in the digestive system; indicators of your body’s toxic load and ability to support detoxification; and key communicators that your brain and nervous system use to support your mood and stress response.

Nutrient Deficiencies

Micronutrient Testing by Vibrant America – provides a comprehensive extracellular (nutrients in your blood stream) and intracellular (nutrients inside your cells) assessment of the levels of the most important vitamins, minerals, antioxidants, fatty acids and amino acids. This test can help target nutrient deficiencies related to fatigue, thyroid imbalance, hormone imbalance, metabolism, immune system imbalance, skin problems and numbness and tingling symptoms. It’s great for those on restricted diets for digestive health or vegans who may need to supplement with certain nutrients.
