Functional Diagnostic Nutrition: Customer Service software

Functional Diagnostic Nutrition offers a training program that teaches practitioners how to use functional lab testing and systematic health protocols.

What is Functional Diagnostic Nutrition?

Functional Diagnostic Nutrition, founded by Reed Davis, is an educational curriculum and practical methodology centered on functional health investigation. Developed through 10 years of clinical observations and refined across 17 years, the program trains health coaches and wellness professionals to use objective diagnostic data rather than relying on symptom-based trial and error. The framework teaches practitioners to analyze laboratory data systematically, identifying multiple underlying cellular stressors across interacting body systems to support total health recovery.

The cornerstone of the methodology relies on an investigative framework called H.I.D.D.E.N. This protocol evaluates six vital biological areas: hormone regulation, immune activity, digestive function, liver detoxification pathways, cellular energy production, and autonomic nervous system balance. FDN trains students to implement a foundational core of 5 functional lab tests to evaluate these areas concurrently. Once biological imbalances are revealed, practitioners apply the D.R.E.S.S. framework to build individual client plans incorporating diet, rest strategies, exercise, stress reduction, and targeted supplementation.

To assist non-licensed health practitioners, FDN operates the Medical Director Program. This structure provides trainees and graduates with access to order more than 70 functional diagnostic tests without possessing an independent medical license. Laboratory options cover stress profiles, mucosal barrier assessments, GI-MAP stool panels, metabolic typing, and mediator release testing. Diagnostic orders are placed through direct laboratory relationships or third-party distributors, with licensed clinical advisors available to review test results alongside the practitioner.

The learning model is self-paced and hosted within an online student portal. Students begin by serving as their own primary client, running foundational laboratory tests on themselves to experience the investigative process directly. The program incorporates 12 private mentorship sessions with experienced practitioners who guide trainees through portal logistics, personal laboratory interpretation, and clinical case study reviews. Trainees who finish the curriculum within 12 months receive permanent access to learning modules and ongoing content updates.

In addition to clinical instruction, the program delivers business development training to assist graduates in launching an independent consulting practice. The Business 101 curriculum outlines step-by-step procedures for client intake, onboarding workflows, service structuring, and pricing setting. Rather than focusing on complex administrative theory, the business modules prioritize securing and servicing a practitioner's first 10 clients. FDN also hosts live educational events, including 5-day workshops dedicated to specialized clinical topics and laboratory analysis.

Functional Diagnostic Nutrition use cases

Accessing Functional Diagnostics Without a License

Unlicensed health coaches and wellness professionals utilize the Medical Director Program to order functional lab tests for their clients. Operating under licensed medical director oversight, practitioners can request over 70 functional tests, including DUTCH, OAT, HTMA, and GI-MAP panels. This setup permits non-licensed coaches to access diagnostic data without holding an independent medical license or referring clients out to external providers.

Assessing Multi-System Metabolic Dysfunction

Practitioners employ the H.I.D.D.E.N methodology to analyze chronic health challenges systematically. Instead of addressing isolated symptoms, practitioners run a 5-lab foundational testing framework. This protocol evaluates hormone levels, immune function, digestive health, detoxification pathways, energy generation, and nervous system balance simultaneously. Gathering broad diagnostic data allows practitioners to pinpoint multiple healing opportunities at once and design targeted lifestyle interventions.

Gaining Firsthand Experience as a Client

Enrolled trainees act as their own first client during the certification course. Trainees order and complete foundational lab screenings on themselves, experiencing the intake and assessment process firsthand. They analyze their personal lab results alongside an experienced mentor across three dedicated personal health mentorship sessions. This practical approach builds confidence in test logistics, result interpretation, and protocol application before practitioners take on public clients.

Launching an Independent Practice with First 10 Clients

Career changers and new health practitioners use the Business 101 curriculum to establish an active wellness consulting business. The training focuses on execution, providing a step-by-step guide to handle client intake, structure onboarding calls, present protocols, and set fee structures. This practical focus gives practitioners the tools required to acquire, process, and successfully manage their initial 10 clients.

Supporting Clients Taking GLP-1 Medications

Practitioners participate in live training events, such as GLP-1 Practitioner Week, to expand their clinical capabilities around modern health trends. The 5-day event trains practitioners on how to support clients who are currently taking GLP-1 medications, transitioning off them, or seeking alternative wellness strategies. Practitioners learn to manage side effects, apply dietary guidelines, address nutritional needs, and deliver comprehensive lifestyle coaching.
