Woman with vile of blood doing testing

Blood testing is the foundation of modern medicine and the most widely available form of testing for both patients and practitioners. In this course, you’ll learn how to use Functional Blood Testing to prevent and reverse chronic disease and dramatically improve your patients’ quality of life. Functional Blood Testing is the best way to get started with Functional Medicine if you’re new or expand your skill set if you’ve already taken other Functional Medicine courses.

Here are some highlights of what you’ll learn in this practical and experiential course:

  • How (and why) to use Functional Blood Testing as a screening tool to prevent and reverse disease—rather than just manage symptoms
  • The critical difference between Functional and conventional lab ranges and how to interpret blood tests through a Functional Medicine lens
  • Our recommended blood chemistry panel and how to order it for your patients
  • The most common blood chemistry patterns you’ll see in your practice—and how to treat them successfully
  • Real-world case studies to help you immediately apply what you’re learning in your clinic

"Even though I took [a different Functional Medicine course], I never quite got all that they were teaching and did not know how to apply it in practice beyond basic things. With your course, I feel the mystery is gone and I am actually applying what I learn daily and changing people’s lives. Again, thank you." Donna Kay Jennings, BSN, MHSA, MSN, PMHNP-BCMissoula, MT

Anthony Gustin
I can't think of a better decision that has been more worth it than enrolling in the Kresser Institute.
"The knowledge, application, and business sense will all put you a step ahead of the game in every single area. You are literally taking shortcuts to paths in so many industries beyond just Functional Medicine. I went from stressed out working 80 hours in my clinic a week to complete freedom of my schedule to be able to focus on research, learning, and providing greater value to more and more people. I can't believe how quick the transformation was. Since I started the training, I've used the core business principles to quadruple the revenue from my business." Anthony Gustin, MS, DCAustin, TX

An innovative approach to learning

The traditional methods for learning (which you were taught in school) don’t work. So we don’t use them. No “firehose” of information. No brute-force memorization. These methods don’t help you actually absorb or use information. Instead, we use the “sprinkler” method:

  • Content is delivered a little bit at a time, over a longer period of time.
  • Topics unfold in a way that mimics how you will apply them later.
  • Lesson-specific quizzes increase comprehension and retention.

Audit-only version of the course for health enthusiasts

We are offering an audit-only version of the course for non-licensed or licensed health professionals who do not meet the course eligibility criteria but want to learn more about Functional Blood Testing. This course was created for practitioners with the understanding that they have had basic training and education in biology and pathophysiology. There are no entry-level explanations of biology included in these courses, and patient- and clinician-specific resources will not be included in this version, in addition to the following changes:

  • 16 lessons instead of 18
  • No patient case studies (the missing two lessons)
  • No clinician- or patient-specific handouts or handout generator access
  • No eligibility for ADAPT Functional Medicine Practitioner Certification or ADAPT Functional Medicine Practitioner Training full program access
Woman learning via online course

This program was created by a globally renowned clinician, bestselling author, and widely respected authority in the field of Functional Medicine.

Frequently Asked Questions

How will the course materials be delivered to me?

Upon registration for the course, you will receive information by email on how to log in to the course learning portal. The learning portal is viewed through your browser, so all you need is an internet connection and a computer or mobile device. We recommend the Google Chrome browser, but any up-to-date browser and operating system should work just fine. The course is compatible with Mac and Windows computers and iOS and Android devices.

Inside the learning portal, you’ll find the course materials divided into lessons. Each lesson consists of video presentations, along with audio files and transcripts of the presentations, so that you can study the material in the way that best suits your unique learning style. You’ll also find handouts, quizzes, and links to additional resources. Audio files, transcripts, and handouts can all be downloaded to your computer for offline viewing.

How long will I have access to the course?

You’ll have access to the course for 18 months from the time that you register for the course. You can download course materials that you wish to save for a longer time period.

Will I get live support in this course?

No, this course does not have live support. It was created as a self-study course so that you have complete control of your learning experience. You have access to all course materials from day one, and you can choose the order in which you learn the material, how fast you progress through the course, and when you need to take breaks. This type of course is best for the solitary learner who does not wish to interact with course faculty or fellow students. While this course does not provide direct contact with faculty or students, our technical support team is standing by if you have any issues accessing the course. This is also the advantage of case-based learning: you get that in-person, faculty-led discussion feel but on your own schedule.

How can I take the full ADAPT Functional Medicine Practitioner Training and Certification Program and become certified after completing this course?

After completing the Functional Blood Testing course, you can apply to enroll in the full ADAPT Functional Medicine Practitioner Training and Certification Program during one of our open enrollments (which typically happen in the spring and fall). We will apply the cost of the Functional Blood Testing course toward the full tuition price for the complete program. The course material and quizzes that you take during the Functional Blood Testing course will be applied toward certification after completing the remainder of the ADAPT Functional Medicine Practitioner Training and Certification Program.

How long will it take me to complete this course?

You have up to 18 months to complete this course, but the pace you choose is up to you. You can dive right in and do an hour a day and complete the course in six weeks or spread it out over 16 weeks as initially designed.

Can I receive continuing education credit?

No, this course does not offer continuing education credit. This was an intentional decision, as including continuing education units significantly limits the real-world application of the course material.

Is this training suitable for international practitioners?

Yes! We’ve had over 100 international practitioners from 28 countries complete the program. Blood testing is the most widely available form of testing and should be available to practitioners all over the world.

Note that some tests and supplements may be difficult to order in countries outside of the United States, but we have you covered. We provide a reference guide for ordering supplements and labs internationally. For the blood chemistry unit, we teach lab ranges and values in U.S. units, but we provide unit conversion resources.

Due to the variability and evolving regulations for different licenses within each country, we cannot guarantee the relevancy of every aspect of the program for each individual international practitioner. We encourage you to email us if you would like to discuss the details of your unique situation.

What is the best way to reach customer support with questions?

You can contact our customer support team at support@chriskresser.com, and we’ll be happy to answer any questions you have! The ADAPT Functional Blood Testing terms and conditions may answer some of your questions.

What if I find that this course isn’t a good fit for me after purchasing?

Please contact our support team within seven days of your course registration date to apply for a refund.

Will you offer scholarships, financial assistance, or payment plans?

At this time, we do not offer scholarships, financial assistance, or payment plans for this course.
