Quick answer. Autonomic Response Testing (ART) is the structured, repeatable muscle-testing protocol developed by Dr. Dietrich Klinghardt that reads the autonomic nervous system's response to specific stimuli — pathogens, toxins, organs, emotional charges. It's used by Klinghardt-trained clinicians as a sequencing tool on top of (not instead of) conventional functional labs. Only a small group worldwide holds the full mastery certification.
Who Is Dr. Dietrich Klinghardt?
Dr. Dietrich Klinghardt, MD, PhD, is one of the most respected figures in integrative medicine worldwide. Trained as both a physician and a researcher, he spent decades synthesizing what conventional medicine kept ignoring: the role of chronic infections, heavy metals, environmental toxins, and unresolved trauma in chronic illness.
He's best known for pioneering treatment frameworks for Lyme disease, co-infections, mold illness, autism spectrum, and complex chronic illness — conditions that mainstream medicine routinely fails to resolve.
But Klinghardt's most enduring contribution may be the diagnostic tool he built to actually find what's driving these illnesses: Autonomic Response Testing.
What Is Autonomic Response Testing (ART)?
Autonomic Response Testing — usually abbreviated ART — is a refined form of bio-energetic muscle testing that reads the autonomic nervous system's response to specific stimuli (substances, frequencies, organs, emotional charges).
Unlike crude "applied kinesiology," ART is a structured, repeatable protocol that filters out interference patterns (scar tissue, geopathic stress, electromagnetic load, retroviruses, emotional blocks) before drawing any clinical conclusion. Done correctly, it gives the practitioner a real-time map of:
- Which pathogens (Borrelia, Bartonella, Babesia, viruses, parasites, mold) are active
- Which organs and tissues they're hiding in
- Which toxins (metals, biotoxins, glyphosate, plastics) are blocking healing
- Which specific remedies, dosages, and sequences the body will actually respond to
- Which emotional or ancestral pattern is locking the case in place
Why ART Matters for Chronic Illness
Standard labs are extraordinary at acute disease and terrible at chronic complexity. Lyme tests miss half the cases. Mold tests miss biofilms. Heavy metal panels miss intracellular load. Stool tests miss the upper GI.
ART doesn't replace labs — it sequences them. It tells the practitioner what to test, in what order, and what to do with the answer. That's why Klinghardt-trained clinicians get traction on cases that have already been through 8 specialists.
Why So Few Practitioners Have True Klinghardt Mastery
Klinghardt's full curriculum is not a weekend course. To reach mastery a practitioner must complete, in person, over many years:
- ART Levels 1–4 (the diagnostic backbone)
- Klinghardt Lyme & co-infection protocols
- Chronic illness curriculum (mold, heavy metals, retroviruses, KPU)
- Family Constellation Work (Klinghardt's adaptation of Bert Hellinger's method for ancestral and systemic trauma)
- Neural therapy, mental field therapy, and matrix work
Each level requires testing, case review, and direct mentorship. Worldwide, only a small group of practitioners has finished the entire arc. Most who claim "Klinghardt training" have done one or two seminars — not the mastery track.
Where Dr. Nick Fits In
Dr. Nick Carruthers is one of the rare practitioners who completed the full Klinghardt mastery path — ART through Level 4, Lyme and co-infection training, the chronic illness curriculum, and Family Constellation work.
But he didn't stop there. After two decades of integrating Klinghardt's framework with Matrix Energetics, Quantum Medicine, Quantum Energetics, the Demartini Method, and Dr. Brimhall's work, he developed two original diagnostic and treatment systems of his own:
- Integrative Response Testing (IRT) — a next-generation evolution of ART that layers quantum-field testing on top of the autonomic readout, dramatically tightening signal accuracy on the hardest chronic cases
- Biointegration Technique — a treatment method that integrates the physical, energetic, emotional, and ancestral layers in a single session, instead of treating them as separate appointments
This is the diagnostic engine running underneath every Private Concierge case and informing every advanced protocol inside the Integrative You programs.
Lyme, Co-Infections, and Why Most Treatment Fails
Lyme disease is the textbook example of why ART exists. It rarely travels alone — Bartonella, Babesia, Mycoplasma, viral reactivations (EBV, HHV-6), mold, and heavy metals usually co-pilot the illness. Antibiotic-only protocols miss the co-infections, ignore the toxic load, and never address the nervous system pattern that's keeping the immune system stuck.
Dr. Nick and Dr. Nicole Rivera specialize in exactly this terrain: Lyme, co-infections, mold, and chronic illness that hasn't moved despite years of treatment elsewhere.
Is ART-Level Care Right for You?
You may benefit from a Klinghardt-informed, IRT-driven workup if:
- You've been chronically ill for 2+ years without a clear root cause
- You suspect or have been diagnosed with Lyme, mold, or heavy metal toxicity
- You've cycled through specialists, supplements, and protocols with limited progress
- You sense there's an emotional or family-systemic layer your medical team isn't touching
Where to Start
Most members start with a Health Decode to map the obvious blind spots, then move into DNA Precision for epigenetic and toxicity mapping. The most complex cases — true Lyme, mold, and chronic illness — work directly with Dr. Nick inside Private Concierge, where IRT and Biointegration are deployed in full.

Frequently Asked Questions
Is Autonomic Response Testing the same as applied kinesiology? No. ART is a structured, repeatable protocol that filters interference patterns (scar tissue, EMF load, metals, emotional charge) before drawing any clinical conclusion. Generic applied kinesiology skips that filter and produces unreliable readings.
Is ART evidence-based? ART itself is mechanism-of-practice; the underlying physiology (autonomic reactivity to stimuli) is well-established. The honest read: ART is a clinical sequencing tool that tells the practitioner what to test next on conventional labs. It is not a replacement for blood, urine, stool, or imaging diagnostics, and we never present it as one.
Who actually holds Klinghardt mastery? Worldwide, only a small group. The full path is ART Levels 1–4, the Klinghardt Lyme and co-infection curriculum, the chronic-illness curriculum (mold, metals, retroviruses, KPU), Family Constellation Work, and neural / matrix therapy — all in-person, over years. Most practitioners who claim "Klinghardt training" have done one or two seminars.
Can ART help with mold and heavy-metal cases? Yes — those are two of the cases where it most reliably changes outcomes, because conventional labs miss intracellular load and biofilm-bound toxins. See our mold protocol — 2026 update and heavy-metal protocol with modern binders.
How is bioresonance different from ART? Bioresonance is device-driven; ART is practitioner-driven. Both are bio-energetic, both filter for interference, and both work best as sequencing tools on top of labs. Read our bioresonance therapy pillar for the side-by-side.
