A.R.T. in Central London and Hertfordshire

Autonomic Response Testing — a diagnostic system that listens to your body's own intelligence.

A.R.T. is a quantum biofeedback system that reads the light emissions your cells produce to assess your health across all five levels of healing — physical, energetic, mental, intuitive and spiritual. Non-invasive and deeply precise, it reveals the hidden root causes of illness that conventional medicine cannot reach.

Find the cause. Feel the change.

The Foundation

Your autonomic nervous system knows more than any lab test

Autonomic Response Testing (A.R.T.) is a sophisticated biofeedback-based assessment developed by Dr. Dietrich Klinghardt, MD PhD. It works by reading the autonomic nervous system — the part of your body that governs heart rate, immune response, digestion, detoxification and more — as a diagnostic instrument.

Rather than treating symptoms in isolation — or just masking symptoms — A.R.T. seeks the underlying stressors that have caused your nervous system to enter a state of "blocked regulation" — the root condition behind most chronic illness. It integrates principles from applied kinesiology, biophoton physics, and traditional Chinese medicine into a single, coherent diagnostic framework.

"Most chronic illness has multiple drivers. A.R.T. tests for all seven systematically — uncovering combinations and interactions that no single lab test or specialist consultation could reveal alone."

Dr. Dietrich Klinghardt, MD PhD

Conditions Treated

What A.R.T. can reveal & address

Most chronic conditions don't begin with a diagnosis — they begin with silent disruptions accumulating over years. A.R.T. is one of the few systems capable of detecting and mapping these disruptions precisely, then verifying the exact remedies your body needs to restore balance.

A.R.T. is particularly valuable for those who have not found resolution through conventional medicine — people with complex, multi-system, or long-standing conditions where the cause has remained elusive.

Our Approach

Assess. Understand. Remedy.

Three steps to uncovering what is really happening in your body — and the bespoke protocol to address it.

Assess

A.R.T. reads your autonomic nervous system to reveal hidden stressors, toxins, and imbalances that standard tests miss — across all five levels of healing.

Understand

We identify not just what is present, but why a disease process has taken hold — mapping the biological terrain, uncovering the underlying drivers, and addressing imbalances before they become the chronic conditions that conventional medicine struggles to treat.

Remedy

Receive a bespoke protocol — supplements, homeopathics, herbal medicine, detoxification support, psycho-emotional work, dietary & lifestyle advice — verified against your unique physiology. No guesswork.

About Qfive Healthcare

Precision, compassion, and deep personalisation

We work with clients who have often spent years navigating the NHS or private medicine without resolution — people with complex, multi-system, or long-standing conditions where the root cause has remained elusive. If your tests come back "normal" but you know something is wrong, A.R.T. may be the assessment you have been looking for. We also work with those who are in good health and wish to stay that way — using A.R.T. to identify emerging imbalances and address them long before they become disease.

Our approach is grounded in Dr. Klinghardt's Autonomic Response Testing methodology — one of the most sophisticated biofeedback diagnostic systems available. Every session is wholly tailored to your unique physiology, history, and healing goals.

With clinics in Central London and Hertfordshire, Qfive Healthcare is a private practice dedicated to those who demand more from their healthcare — and who are ready to address the root causes of their chronic illness, not just manage its symptoms.

Treatment Modalities

Protocols used at Qfive Healthcare

Based on A.R.T. findings, treatment is selected and verified against each individual's responses. Protocols may include any combination of the following:

Targeted Supplementation

Individually verified vitamins, minerals, enzymes and nutraceuticals — tested for suitability and correct dosage before recommendation.

Herbal Medicine

Antimicrobial, adaptogenic and detoxifying herbs — verified by A.R.T. to ensure they support rather than burden your system.

Detoxification Support

Heavy metal chelation, mould protocols, and drainage support — sequenced carefully so the body can safely eliminate identified toxins.

Psycho-Emotional Work

Applied Psycho-Neurobiology (APN) and trauma-informed techniques to address the emotional and subconscious drivers of physical illness.

Lifestyle & Dietary Guidance

Personalised nutritional strategies, EMF mitigation, sleep hygiene, and environmental changes — all verified to support your specific healing process.

Manual Therapy

We offer Douglas Heel's Be Activated technique — a powerful manual therapy that resets the body's neurological sequencing, releasing deeply held muscular and fascial patterns. By reactivating the correct muscle firing order, Be Activated restores the body's optimal movement, reduces compensatory pain, and supports the nervous system's capacity to heal.

Client Experiences

What our clients say

★★★★★

"My son was repeatedly seriously ill — days of high fever, blisters across his throat, unable to eat. A.R.T. traced it back to the root cause: Covid had reactivated an underlying virus that kept making him unwell. Treated with natural remedies for both, he has been entirely symptom-free for 18 months."

★★★★★

"During the assessment, Sarah and Dede identified something that needed urgent attention. Blood tests confirmed it. Through their care, we addressed it and I've now been given the all clear. I owe them more than words can say."

★★★★★

"I was sceptical at first, but after following their protocol and seeing dramatic changes to my chronic skin issues within the first week of treatment, I am filled with confidence about the rest of my health journey."
