APRIL 13-15, 2018


Day 1

The Clinical Significance of Organic Acids Testing

Learn how to use this comprehensive metabolic test in your practice to help your patients with a variety of chronic health conditions.  Find out how the OAT helps you discover underlying causes of many symptoms and hear what kinds of treatments have been effective.  Qualified attendees at the Organic Acids Testing Workshop receive a FREE Organic Acids Test, worth $299!

Day 2

The Health Implications of Metal and Non-Metal Toxins

This workshop will focus on the epidemic of environmental toxin exposure, from the many chemicals we encounter every day, to heavy metals, to mycotoxins released from mold. You will learn about many common environmental pollutants from the 172 chemicals tested by our GPL-TOX Profile.  You will find out how these chemicals can affect our health and what steps can be taken to help detoxify the body.  You will also learn about the seven types of mold mycotoxins tested for in our new GPL-MycoTOX Profile and about the chronic health conditions mycotoxin exposure can cause.  We will review how to use these tests in your practice to create the most effective treatments possible for your patients. 

Day 3

The Inflammatory Basis of Disease

Using Specific Tests to Discover and Treat Chronic Inflammation
Inflammation has been implicated in many different chronic diseases and can occur in almost every tissue of the body.  Prevention and reduction of inflammation can often lead to better health outcomes.  The Great Plains Laboratory has focused on how inflammation can be managed for numerous types of chronic diseases, from depression and Alzheimer’s disease, to fibromyalgia and cardiovascular disease, and this all started with the Organic Acids Test.  We then developed our Phospholipase A2 Activity Test because of PLA2’s inflammatory role in many chronic diseases.  Finally, we provide an IgG Food Allergy Test and a Gluten + Casein Peptides Test to assist in determining how diet can lead to inflammation and chronic disease.  On day three, we will review how all of these tests can be used to discover sources of inflammation in the body and brain, as well as treatments that have been effective.



organic acids testing

8:00am | Registration and Breakfast

8:45am | An Overview of Organic Acids Testing and Its Importance

Hundreds of organic acid metabolites are found in the urine of all mammals, including humans. These metabolites can be used for both diagnostic and therapeutic measurements for detecting abnormal gastrointestinal overgrowth or dysbiosis, assessing mitochondrial energy production, detecting genetic diseases, assessing malnutrition and suboptimum nutrition, revealing toxic exposure, finding alterations of neurotransmitter metabolites in neurological and psychiatric disorders, and assessing metabolites that cause severe inflammation in a variety of chronic illnesses.

The OAT evaluates for various fungal toxins, including specific markers for Candida. Many people rely on stool testing for Candida diagnosis and miss the presence of Candida toxins through the Organic Acid Test. Candida can lead to neurochemical imbalances in the brain, as well as sensory problems and self-stimulatory behavior (often seen in autism).

11:15am | Morning Break

The OAT evaluates for two specific toxins related to Clostridia bacteria – HPHPA and 4-cresol. Both of these toxins can inhibit a dopamine converting enzyme, leading to excess dopamine and toxic reactions in the brain and nervous system. Problems such as moodiness, irritability, aggression, self-injurious behavior, sleep difficulties, and more can be associated with Clostridia bacteria overgrowth.

12:45pm | Lunch

1:45pm | the role of oxalate toxicity in chronic health problems

The OAT includes glycolic and glyceric acids in the oxalate section, which can differentiate between genetic and nutritional components in disturbed oxalate metabolism. Oxalates are compounds found in many foods, and can be worsened by Candida overgrowth. High oxalates are associated with pain in the joints, muscles, and connective tissues. They can also trap heavy metals (such as mercury, lead, and arsenic) in the body and lead to mineral imbalances. Certain behavioral issues and self-injurious tendencies have been associated with high oxalates.

2:30pm | neurochemical imbalances and quinolinic acid toxicity

The OAT evaluates for imbalances in serotonin (an important brain and nervous system chemical for mood, fine and gross motor skills, and calmness), as well additional markers that can indicate toxic stress in the brain and nervous system, such as quinolinic acid. High quinolinic acid suggests toxic stress in the brain and is important to evaluate before prescribing certain supplements, particularly L-Tryptophan which is commonly used to help with sleep.

3:30pm | Afternoon Break

4:00pm | case studies and treatment options

This presentation will highlight various patient cases from clinical practice that show the role of biomedical intervention for various patient scenarios such as dietary therapy, yeast and Clostridia treatment, and methylation support.

Day 2

The Health Implications of Metal and Non-Metal Toxins

8:00am | Breakfast

8:30am | Non-Metal Toxic Chemicals and Their Effects on Health

A huge array of non-metal toxic chemicals like phthalates, pyrethrins, organophosphates and many others can now be tested conveniently and economically in a single morning urine sample. Learn how to use this testing and apply it to a wide variety of chronic illnesses such as neurological disorders, psychiatric disorders, chronic fatigue, and many others. The best treatment options will be presented in great detail.

9:45 am | Glyphosate, 2,4-D, GMO Foods, and the Microbiome

The widely used weed killer glyphosate (Roundup™) has been implicated as a cause of chronic kidney disease and cancer. Exposure to glyphosate may alter the microbiome of all of our agricultural soil and seriously alter the intestinal flora of humans and farm animals. Learn how GMO foods are connected with a wide variety of other chronic illnesses because of glyphosate contamination.

11:00am | Morning Break

11:30am | Invasion of the Brain Snatcher: Environmental and Infectious Influences on the Brain

Do your patients really have a "mental illness" like OCD or depression, or is it an infection or toxins affecting their brains? This presentation will explore the work-up and effects of environmental toxins and infections on the brain and mental health.

1:00pm | Lunch

2:15pm | The Hidden Threat of Mycotoxins, Part 1

Mold and fungi are ubiquitous in the environment. However, in "WDB" (water damaged buildings), and even some foods, mold can become a sinister force affecting physical and mental health. Not all molds are toxic and many just cause respiratory issues, but a subset of molds produce mycotoxins; powerful neurotoxins that can have a profound effect on the brain and mental health. The effects of mycotoxins, as well as testing, diagnosis, and treatment options will be discussed.

3:30pm | Afternoon Break

4:00pm | The Hidden Threat of Mycotoxins, Part 2

This presentation will review the specific markers in the GPL-MycoTOX Profile and how you may use this test in your practice to help your patients with mold exposure.

4:30pm | Heavy Metals and Their Role in Chronic Health Disorders

Heavy metals like cadmium, lead, and mercury are associated with many chronic illnesses and cancer. Find out the best way to test these metals, as well as simple protocols for treatment of excessive exposures.

Day 3

The Inflammatory Basis of Disease

8:00am | Breakfast

8:30am | Important Risk Factors for Alzheimer's Disease

Recently, Alzheimer’s disease has been successfully treated by optimizing a variety of biochemical factors including fats, vitamins, minerals, inflammatory markers, and toxicity markers. These tests, as well as treatments based on test results will be reviewed.

9:30am | Fatty Acids and Cholesterol in Mental Health

Deficiencies of total cholesterol and/or omega-3 fatty acids have been implicated in a number of psychiatric diseases including autism, AD(H)D, depression, Alzheimer’s disease, bipolar depression, and road rage. The significance of testing for these fats and methods to optimize these fats to prevent or treat various illnesses will be explored in detail.

10:30am | Morning Break

11:00am | PLA2: The Possible Root Cause of Many Inflammatory Disorders

Phospholipase A2 (PLA2) is elevated in a variety of inflammatory conditions including multiple sclerosis, cardiovascular disease (including atherosclerosis), Crohn’s disease, neurodegenerative diseases, bipolar depression, schizophrenia, and sepsis. This section will review new information about PLA2, methods for PLA2 testing, and treatment options.

11:30am | How Peptides Affect Chronic Health Issues

Peptides are small proteins that have profound effects on eating behavior, digestion, pain, immunity, infection, addiction, and more. We will review some of the most well-researched peptides such as the opiate peptides from wheat, milk, and soy.

12:00pm | Lunch

1:00pm | Food Allergy Testing: Scientific Evidence of its Validity in Chronic Illness

IgG food allergy has been implicated in a wide variety of illnesses including chronic fatigue, irritable bowel syndrome, obesity, autism, depression, schizophrenia, migraine headache, and many others. Learn about the different types of allergy testing and the treatments for allergies.
