They are dedicated to assisting healthcare practitioners make a difference by helping people to achieve their maximum potential through quality laboratory testing. Their laboratory provides the most reliable, comprehensive, and understandable scientific results, using the latest technology and proven techniques.
Flagship Test: The Organic Acids Test (OAT)
The Organic Acids Test (OAT) offers a comprehensive metabolic snapshot of a patient’s overall health with over 70 markers. It provides an accurate evaluation of intestinal yeast and bacteria.
Abnormally high levels of these microorganisms can cause or worsen behaviour 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.
Great Plains’ 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.

Featured Video: Testing for Mycotoxins
Mycotoxins are toxic compounds that are naturally produced by certain types of moulds (fungi). Moulds that can produce mycotoxins grow commonly in the environment in particular on foodstuffs and can be detrimental to health.
Watch the webinar snippet below to learn more about when you should consider mycotoxin testing for your patient and how to test for mycotoxins in urine.

Featured Tests
The Organic Acids Test
- Over 70 markers
- Accurate evaluation of intestinal yeast and bacteria
- Includes markers for oxalates
- Identify correlation to multiple select disorders
- Includes markers for Clostridia
GPL-Tox
- Screens for 172 different environmental pollutants using 18 different metabolites
- Uses the power of advanced mass spectrometry (MS/MS), which is necessary to detect lower levels of certain genetic, mitochondrial and toxic chemical markers that conventional mass spectrometry often misses.
- Includes Tiglylglycine, a marker for mitochondrial damage, which is often seen in chronic toxic chemical exposure.
- Pairs perfectly with the Organic Acids Test (OAT) and Glyphosate Test.
GPL-Mycotox profile
- Screens for eight different mycotoxins, from four species of mould, in one urine sample
- Uses the power of advanced mass spectrometry (MS/MS), which is necessary to detect lower levels of these fungal toxins
- GPL-MycoTOX can be pared with Organic Acids Test (OAT), GPL-TOX and the Glyphosate Test to give a comprehensive insight into the levels of exposure to common environmental toxins and the damage that may be caused by this exposure.
IgG Food Map
- An easy, cost-effective and reliable way to measure IgG (1-4)
- Includes a Candida Albicans marker
- All 4 IgG Subclasses Tested (IgG 1-4)
- Exemplary Industry Accuracy using xMAP technology
- Easy to read report
- Assesses 190 Foods
Glyphosate Test
- Glyphosate is the world’s most widely produced herbicide and is the primary toxic chemical in Roundup™, as well as in many other herbicides.
- Glyphosate has been classified by The WHO as a probable carcinogen in humans.
- Can be added on to the GPL-TOX.
