The Ortho-HOD Pro test is a combined test that encompasses 2 parts.
The first part is a test developed by Drs. Abram Hoffer and Humphrey Osmond that gauges perception and depression. Previously known as the HOD (Hoffer-Osmond Diagnostic) test, it is a series of 145 true/false questions designed to measure errors of perception. It will also reveal whether or not medical cannabis prescription is contraindicated.
The second part of the Ortho-HOD Pro test is a series of 39 true/false questions that give insight into areas of brain chemistry that may be deficient and can be corrected with targeted nutrition (also listed). These results also provide clues to physicians regarding lab workup requirements where necessary.
