Great course
The software is amazing for analysing bloods. It's so in-depth. The course is full of information. I prefer the practical side of it more so than the detailed bio chemistry but it is designed for doctors so I appreciate that.

I have taken several courses relating with functional medicine. I have gone through a few certification programs as well. This course was probably the most informative for all things blood work! There are several reasons why you should consider this course: it is self-paced, affordable for what you get, accessible, empowering and informative in many ways more than just "here is a marker, next marker please".... There is a lot of emphasis on mechanisms of action. Because it is so rich in content, I know I will be going back to the info as I get more and more clinical experience. The tools are great as well!

I was one of the first users of the Optimal DX program and I and highly recommend it to all practitioners of functional medicine. The software is an invaluable tool that gives me the ability to explain lab findings from a functional perspective and provide patients with detailed information about lab findings.

In today's world, bloodwork has been thought of as a tool to diagnose and treat a pre-existing condition. On the other side of the spectrum is Dr. Weatherby's Optimaldx program. Speaking of personal experience, it has been a game-changer for myself, my family and for my patients when it comes to being pro-active regarding my healthcare decisions. The functional data not only gives you the tools to gain more knowledge but moreover, it offers hope. Thank you for all that you do and are at Optimaldx!

The Optimal Dx is one of the most significant, if not thee most significant development in my naturopathic medical practice. I have been a customer of Dr. Dicken Weatherby since the beginning of my practice 17 years ago. I have been using the ODx software since it was developed. It has been amazing for my patients and I! I would highly recommend it! Dr. Weatherby is the most honest businessman/doctor that I know. He goes way and above what is expected! I trust he and his software without hesitation.

I've been using the ODX software since it began in 2012 - initially for my own patients and clients then, after I founded the Institute of Nutritional Endocrinology, with my students and graduates. The software is an invaluable tool that gives us the ability to explain lab findings from a functional perspective, and t formulate nutrition and lifestyle plans to empower patients and clients to restore their health. I even developed a training for my health practitioner students to help them to use the report as an enrollment tool. I love it. Thanks ot Dr. Weatherby and the team for such great work and support.

I have practiced Foundational Health for over 25 years and have to say that our program was greatly enhanced with the introduction of the ODX Blood Chemistry Software in 2012! I was fortunate to have met Dr. Dicken earlier and quickly became an avid student of his teaching on Functional Blood Chemistry Analysis. I was privileged to become one of the first beta testers back when he rolled out his software. It truly changed our practice and more importantly the well-being of my clients. Functional Blood Chemistry Analysis quickly became our “Gold Standard” for evaluating our clients' functional and foundational health. We continue to use this wonderful tool a decade later with all of our clients. I also have clients that continue to order this year after year as an annual follow-up that I review virtually with them! If you are looking for that tool to truly scale your practice, trust me, this is it! All the best in health! Stuart Hoover, NHD Essential2Health
