In this 6-module bootcamp, you will deepen your understanding of organic acid testing and learn how to apply it effectively in clinical practice. We will explore the history and foundational principles behind organic acids testing, as well as its role in assessing cellular health, and you will be able to identify patients who would benefit most from this diagnostic tool. With a focus on practical application, we’ll also review essential biochemistry concepts to enhance your ability to interpret lab findings and confidently integrate the OAp™ test into your clinical workflow.
By the end of the bootcamp, you’ll be equipped to use the OAp™ resource toolkit, design targeted protocols based on test results, and consider complementary lab tests as next steps. Whether you're new to organic acid testing or seeking to refine your skills, this course will provide the knowledge and confidence to optimize patient care.
