ADAPT FUNCTIONAL BLOOD TESTING
Stop Reading Labs.
Start Interpreting Them.
Learn the functional medicine pattern recognition system that reveals root-cause dysfunction in standard bloodwork.
A self-paced, 40-hour Functional Blood Testing course that teaches you to read between the lines of standard labs.
- 18 on-demand lessons
- Case-based application
- Clinical protocols and practitioner tools
- Available standalone or part of the FMP-AC certification pathway
Join 2,000+ practitioners who’ve transformed their diagnostic confidence.

Most Functional Medicine training is theory-heavy, not practical.
It teaches the “why” but not the “how,” leaving clinicians with theory but not enough practical skill to interpret labs or make confident decisions.
What’s missing from most programs is a systematic way to use everyday bloodwork to:
- Order relevant tests
- Spot dysfunction early
- Find underlying drivers
- Build personalized protocols
- Improve outcomes affordably
Adapt is different. We focus on application, pattern recognition, and clinical decision-making you can use the next day in practice.

For Practitioners Who Want to Go Beyond “Normal” Labs
Blood chemistry is the first and most essential diagnostic tool in Functional Medicine. It’s where root-cause investigation begins.
The Adapt Functional Blood Testing Course gives you a clear, practical method for interpreting standard labs through a functional lens, so you can catch dysfunction earlier, prevent progression, and deliver more precise treatment plans.
By the end of this course, you’ll be able to:
Use blood chemistry as a screening and decision-making tool
Identify early dysfunction years before it becomes a diagnosable disease; helping patients avoid chronic illness rather than manage it.
Apply functional vs. conventional ranges
Understand why standard reference ranges often miss early dysfunction, and how to use functional ranges to guide clinical reasoning.
Order the right blood chemistry panels (and know where to order)
Learn our recommended panel (and variations), plus practical steps for ordering whether you’re licensed, collaborating, or auditing.
See patterns across systems, not isolated markers
Master pattern recognition to correlate markers across metabolic, endocrine, inflammatory, immune, and nutrient systems.
Recognize common blood chemistry patterns quickly
Spot the top clusters you’ll see most often in clinic and link them to actionable root-cause hypotheses.
Apply appropriate nutrition, lifestyle, and supplement strategies
Learn how functional patterns inform personalized treatment planning without over-testing.
Communicate lab findings with clarity and confidence
Help patients understand the “why” behind protocols → increasing buy-in, adherence, and outcomes.
You won’t just memorize markers, you’ll know how to think with them.
What You’ll Learn
The Functional Blood Testing Course is organized into 10 structured modules that build from foundational concepts to systems physiology to real clinical application.
Each module includes:
• Short instructional videos
• Practitioner tools and handouts
• Retention quizzes (Clinical Track)

You’ll walk away with a repeatable interpretive framework you can apply to every single patient from Day 1.

Allie Nowak, PA-C, Faculty
Allie Nowak is a board-certified Physician Assistant who graduated with a Master’s degree from the University of Iowa Carver College of Medicine. She was first introduced to Functional Medicine in 2011 during her capstone undergraduate internship with Dr. Terry Wahls; she experienced firsthand the impact a therapeutic diet and lifestyle can have on patients with relapsing-remitting multiple sclerosis.
The experience not only was eye opening, but forever changed the way she wished to approach her patient’s care. After completing her graduate school coursework, a year of Primary Care, and transitioning to OBGYN, she decided to pursue Functional Medicine training given the gap she saw in standard medical care. She has completed the Kresser Institute Adapt Practitioner Training Program as well as advanced training through A4M in “A Metabolic and Functional Approach to Endocrinology”. She began her Functional Medicine career in OBGYN; however, her practice quickly expanded beyond hormone imbalances to include gastrointestinal issues, poor sleep, fatigue, metabolic problems, and autoimmune disease. She has been a practitioner with the California Center for Functional Medicine since May 2021.
This is real-world, clinician-led training.
Everything you’ll learn is the product of thousands of patient hours and decades in Functional Medicine practice.
