The Great Plains Laboratory, Inc. (GPL) is the leader in metabolic testing for patients with neurological, behavioral, gastrointestinal, and immunological disorders. Our Organic Acids Test is the most comprehensive available on the market with over 70 markers, including those for yeast, bacteria, oxalates, neurotransmitters, vitamin deficiencies, oxidative stress, fatty acids and more. Our toxic, non-metal chemical profile, GPL-TOX, screens for the presence of over 170 different toxic chemicals by testing 18 unique metabolites, including organophosphate pesticides, phthalates, benzene, xylene, vinyl chloride, and pyrethrin insecticides, and also includes a marker for mitochondrial damage. In October 2015, we launched a urine test for glyphosate, the world’s most widely used toxic herbicide. Our newest test, GPL-SNP1000, is a genetic profile that tests over 140 genes and over 1,000 SNPs in nine critical pathways for health. We look forward to par tnering with you to provide your patients with the most comprehensive testing and most personalized treatment plans possible.
