As a holistic nutritionist, you have the knowledge and skills to develop powerful protocols for your clients. However, to make your assessment truly holistic, you must have an understanding of diagnostic and laboratory tests. These tests provide valuable insight into the unique state of each client and offer an objective measure of client progress. This course covers the basics of blood, urine and saliva testing, including tests for liver, kidney and digestion, thyroid and adrenal function, lipid disorders, diabetes, heavy metals and more. Students will gain the knowledge to confidently interpret laboratory results and incorporate them into a holistic plan to increase health outcomes.

DATES: July 14, 21, 28 August 4, 11, 18, 25, September 1, 2026

RECOMMENDED TEXT: Mosby’s Manual of Diagnostic Tests—Dr. David has the 4th Canadian edition in his practice (being that he’s in British Columbia) but any Canadian edition is OK if you are practicing in Canada. The third, published in 2023, is probably ideal. The American version is in its 8th or 9th edition. All of the information that you need will be on the PowerPoint slides but it’s nice to have the digital or hard copy version as a clinical reference. You can buy most versions on Amazon.
