Nutritional Tests

The following tests will help your medical professional establish proper healthy lifestyle changes, including dietary choices, proper supplementation of vitamins, minerals, herbs, and probiotics, as well as exercise prescription based on your individual needs.   

Organic Acids Test (OAT)
Nutritional & Metabolic Profile ($349)

The Organic Acids Test (OAT) offers a comprehensive metabolic snapshot of a patient’s overall health with 76 markers.  It provides an accurate evaluation of intestinal yeast and bacteria.  Abnormally high levels of these microorganisms can cause or worsen behavior disorders, hyperactivity, movement disorders, fatigue and immune function. Many people with chronic illnesses and neurological disorders often excrete several abnormal organic acids in their urine. The cause of these high levels could include oral antibiotic use, high sugar diets, immune deficiencies, acquired infections, as well as genetic factors. Our Organic Acids Test also includes markers for vitamin and mineral levels, oxidative stress, neurotransmitter levels, and is the only OAT to include markers for oxalates, which are highly correlated with many chronic illnesses.

MycoTOX Profile (Mold Exposure) ($299)

Mycotoxins are metabolites produced by fungi like mold, which can infest buildings, vehicles, and foodstuffs. They are some of the most prevalent toxins in the environment. Unfortunately, mycotoxins are resistant to heat and many processing procedures. Diseases and symptoms linked to rheumatic disease, asthma, sinusitis, cancer, memory loss, vision loss, chronic fatigue, skin rashes, depression, ADHD, anxiety, and liver damage. The MycoTOX profile screens for 11 different mycotoxins, from 40 species of mold, in one urine sample. It uses the power of advanced mass spectrometry (MS/MS), which is necessary to detect lower levels of these fungal toxins.

GPL-TOX Profile (Toxic Non-Metal Chemicals) ($219)

Because exposure to environmental pollutants has been linked to many chronic diseases, The Great Plains Laboratory has created GPL-TOX, a toxic non-metal chemical profile that screens for the presence of 173 different toxic chemicals including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, pyrethroid insecticides, acrylamide, perchlorate, diphenyl phosphate, ethylene oxide, acrylonitrile, and more.  This profile also includes Tiglylglycine (TG), a marker for mitochondrial disorders resulting from mutations of mitochondrial DNA.  These mutations can be caused by exposure to toxic chemicals, infections, inflammation, and nutritional deficiencies.


Glyphosate is the world’s most widely produced herbicide and is the primary toxic chemical in Roundup™, as well as in many other herbicides. In addition, in 2014 Enlist Duo™, a herbicide product which contains a 2,4-dichlorophenoxyacetic acid (2,4-D) salt and glyphosate, was approved for use in Canada and the U.S. for use on genetically modified soybeans and genetically modified maize, both of which were modified to be resistant to both 2,4-D and glyphosate. 2,4-D has many toxic effects of its own and can be measured in the GPL-TOX test. Our Glyphosate Test is done via urine sample and can be easily added on to other urine tests like the Organic Acids Test or GPL-TOX at a discounted rate.

IgG Food MAP With XMAP® Technology ($249)

Elevated levels of IgG (Immunoglobulin G) antibodies are associated with a wide variety of illnesses. Symptoms ranging from headache and nausea to seizure and hyperactivity may occur hours or even days after the offending food has been ingested. The complete elimination of IgG positive foods may result in important improvements in symptoms of irritable bowel syndrome, autism, AD(H)D, cystic fibrosis, rheumatoid arthritis, and epilepsy, as demonstrated in numerous clinical studies. 

Our newly updated Food Map IgG Food Sensitivity Profile, now has revolutionary XMAP® immunofluorescent bead technology. It assesses sensitivity to a 190 foods including foods in common American, Asian, and Mediterranean diets. The added hemp marker speaks to the exponential increase in the number of people consuming it as a food source or as medical CBD. GPL has upgraded from the ELISA’s single analyte detection to multiple analyte detection, which has been found to be even more sensitive and more reliable than ELISA tests. The xMAP® bead-based immunoassay is also environmentally friendly, reducing plastic pollution. 


The Dutch Complete™ is our flagship product. 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 (6-OHMS), and 8-OHdG.

DUTCH PLUS® ($499)

The DUTCH Plus® adds salivary measurements of the Cortisol Awakening Response (CAR) to the DUTCH Complete™ to bring another important piece of the HPA axis into focus.


The DUTCH Cycle Mapping™ maps the progesterone and estrogen pattern throughout the menstrual cycle. It provides the full picture of a woman’s cycle to answer important questions for patients with month-long symptoms, infertility and PCOS. Nine (9) targeted estrogen and progesterone measurements taken throughout the cycle to characterize the follicular, ovulatory and luteal phases.

Functional Microbiome Analysis ($399)

BiomeFx is a Functional Microbiome Analysis that measures the balance of pathogens (potentially harmful microbes) and beneficial microbes that make up your gut microbiome. It also reports the potential functions of microbes to better understand how your microbiome could be impacting your symptoms and health concerns. The microbiome in our gut influence’s hormone balance, neurotransmitters, autoimmunity, detoxification, digestion, and disease risk. BiomeFx uses the most advanced and accurate sequencing technology to explore the many inner functions of the gut microbiome and will provide recommendations on improving the balance of your microbes to optimize health and wellness.
