The Great Plains Laboratory, Inc. is pleased to bring you GPL Academy, a series of workshops to help practitioners learn how to integrate our comprehensive testing into their practices.  When you attend a GPL Academy workshop, you will find out why our tests may be incredibly valuable to your practice, what particular markers may be the most meaningful to specific patients, and how to use our tests in tandem to provide your patients with the most personalized treatment plans possible.


The first day of the workshop will focus on the Organic Acids Test (OAT). The OAT from The Great Plains Laboratory is a diagnostic tool that every healthcare practitioner should know about. Whether you are a family practitioner, internist, neurologist, pediatrician, psychiatrist, naturopath, or nutritionist, the information provided by the OAT can be applied to any practice. The OAT provides a comprehensive and accurate snapshot of your patients’ metabolism. More than ever, patients are looking for integrative treatment options for their health concerns. The OAT will greatly enhance your diagnostic abilities with your patients.


On day two, we will focus on the epidemic of environmental toxin exposure, from the many chemicals we encounter every day 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 exposure to these mycotoxins can cause. We will review how to use these tests in your practice to create the most effective treatments possible for your patients.
