“I have been studying functional blood analysis for close to 40 years, and yet I have been so impressed with your course. [...] It helps me to think through and understand the causes behind the dysfunctions and diseases so much more clearly. Thank you for all the time and effort you must have done to make such a fine course”

Gurusahay KhalsaDoctor of Chiropractic

“Dicken, I want to give out a big shout out—your mastery course in functional blood chemistry analysis is great! The 16 week format is doable for everyone. (If I can do it anyone can.)”

Steve EdlingDoctor of Chiropractic

“The FBCA Mastery Training empowers the practitioner with the skills required to recognize numerous patterns and trends within the various systems of the body, enabling one to prioritize their focus. The Optimal Dx software and Functional Health Report is an indispensable, time-saving, educational tool, not only for practitioners but for patients as well!”

L. Humphrey, DNMilton, Ontario CANADA

“The ODX Blood Chemistry course with the certification option was hands down one of the best courses that I have ever taken. I have over 16 certifications and counting and this was top 3 hands down. It packs so much applicable information into 12 weeks that by the time that you are done, it will significantly elevate your blood chemistry analysis skills. Dr. Weatherby's blood chemistry course is broken down nicely as it focuses on fundamentals and it even gets into some pretty advanced topics that are all related to the types of health conditions that practitioners are going to see in today's world and the types of conditions that are not going anywhere any time soon. This course is a great way to fast-track your skills when it comes to scanning blood chemistry and finding healing opportunities and once that takes place then that will also allow practitioners to offer a higher level of care to their clients.”

Travis ZiperHuntington Beach, CA

“This training is a MUST for anyone ready to expand their practice and master the field of Functional Blood Chemistry Analysis. It's truly the best and most comprehensive online FBCA course currently available and Dr. Weatherby is definitely the expert you want to learn from. After years of study, research and teaching, he has the gift of taking a very complex subject and making it understandable, accessible and relevant to clinical practice.

Your practice’s future of accurate functional blood analysis is just 12 weeks away!

1: Intro to Blood Testing & the Functional Approach

 In the first four lessons, you’ll be introduced to the fundamentals of FBCA and go over the best methods for analyzing your patients’ blood test results. You’ll discover what blood test biomarkers you want to see on your panels and how to easily review them with your patients. FInally, we’ll introduce you to the 50+ major metabolic patterns that we will dig into during the rest of the training.

2: G.I. Function

Understanding functionality is key for blood analysis. In these seven lessons, you will dive into the physiology of digestion, absorption and excretion to better understand how these processes affect blood work. Then, we’ll break down dysfunctions and how the role of blood test biomarkers play in uncovering common dysfunctional metabolic patterns for your patients. These patterns play a part in assessing and monitoring patients with hypochlorida, H. pylori, gastric inflammation, pancreatic insufficiency, dysbiosis and intestinal hyperpermeability.

3: Liver & Gallbladder Function

In these six lessons, you’ll dive deep into the functional physiology of the hepato-biliary system. You’ll learn key indicators of oxidative stress and how to identify the five common functional hepato-biliary problems that can be detected with blood tests. Discover how to differentiate complex problems in the biliary tree and the best method for pinpointing liver dysfunction in a patient. Lastly, you’ll learn how to use Functional Blood Chemistry Analysis to uncover systemic toxicity and heavy metal body burden.

4: Red Blood Cell Function & Nutritional Anemias

In these five lessons, you’ll take an in-depth look at red cell function and physiology through the lens of Functional Blood Chemistry Analysis. Explore nutritional anemias and the three minor causes of this condition. We’ll define the biomarker that most practitioners leave out of their analysis, as well discover a relatively new biomarker to assist in assessing for B12 deficiency.

5: Nutrient Deficiencies

Our bodies run on nutrients, which makes them a key part of blood functionality. In these six lessons, you’ll take a look at functional problems associated with vitamin and mineral deficiencies that can be detected with blood tests. You’ll explore the roles of hormone regulation and anion gap in assessing a body’s balance. Finally, you’ll discover how to analyse essential fatty acid deficiencies using biomarkers.

6: Blood Sugar Regulation

In these five lessons, we’ll take a look at the soaring cases of diabetes and obesity and discover how Functional Blood Chemistry Analysis can best flag major blood sugar issues before they become disease. We’ll break down the nine biomarkers you can use to get to the bottom of your patient’s blood sugar regulation issues and uncover the metabolic patterns linked to each stage. Then, we’ll dig deeper into some advanced biomarkers, calculators and new Functional Medicine ratios that will set your practice apart from others.

7: Adrenal & Kidney Function

In these five lessons, you’ll get an in-depth look at the functional physiology of adrenal glands. We’ll look at the regulation of adrenal hormone release and dive into how to use biomarkers on a blood test to look for lifestyle-based adrenal dysfunctions. You’ll explore renal anatomy and physiology and learn how to differentiate kidney dysfunction from kidney disease. 

8: Thyroid Function

In these six lessons, you’ll break down the functional physiology and biochemistry of the thyroid gland to better understand your patient’s thyroid conditions. We’ll review the biomarkers and essential ratios that you must run to assess your patient’s thyroid problems and examine the role each of these biomarkers play in the six metabolic patterns of hypothyroidism. You will dig into the clinical indicators of hyperactive thyroid dysfunction and autoimmune thyroiditis, while learning how to detect these conditions before they manifest into full-blown disease.

9: Cardiovascular Function and Inflammation

These six lessons take a comprehensive look at cardiovascular risk and inflammation. You’ll explore the 20+ biomarkers from a standard blood test that are independent risk factors for early cardiovascular disease and the role that inflammation plays in cardiovascular dysfunction in the body. We’ll take a look at apolipoproteins and the eight specialized biomarkers of the nuclear magnetic resonance (NMR) lipoprofile play in uncovering lipid-related coronary heart disease. Finally, you’ll discover eight new biomarkers that can be measured on a blood test to further assess inflammation.

10: Sex Hormone & Prostate Function

In these six lessons, you’ll take a look at the functional physiology of female and male sex hormone regulation and sex hormone biochemistry. Discover the 12 major sex hormone biomarkers that appear in the blood and learn how to uncover hidden causes of female and male hormone disfunction. You’ll gain a thorough review of the main biomarkers to look for when assessing your patient’s risk of prostate dysfunction.

11: Immune Function

These six lessons will take you through the function and physiology of the immune system. You’ll dive into how to identify the biomarkers that relate to the immune system and how to assess them for immune dysfunction, allergies and immune over-activity. We’ll explore standard immune biomarkers on a complete blood count (CBC) test as well as four immunoglobulins and the two main autoimmune biomarkers. Additionally, we’ll touch on the in-office method of Coca Pulse Testing, which assesses patients for allergies.

12: Putting It All Together

In these final five lessons, we will review all the information from previous lessons and how they all correlate together. You’ll learn how to use blood testing for foundational care, take a look at cash flow in practice, explore how Functional Blood Chemistry Analysis can become a profitable income stream and assist with treatment planning. Finally, in our four case studies, Dr. Weatherby will show you firsthand how to unlock the wealth of information within a blood test.
