Measure the electrical health of every organ system
Electrodermal screening is a family of technologies that measure electrical conductivity at acupuncture meridian points on your hands and feet. Each point maps to a specific organ system, producing a numerical score (0–100) that reveals inflammation, degeneration, or toxin burden — often before conventional labs detect anything.
The original method — Electroacupuncture According to Voll (EAV) — was developed by Dr. Reinhold Voll in Germany in the 1950s and validated across 9 universities worldwide. Today, several device platforms carry this work forward, each with a slightly different approach: classic point-by-point probing (Qest4/Asyra), hand-cradle biocommunication (ZYTO), and frequency-based scanning (AO Scan).
The unique 'indicator drop' phenomenon — when a reading falls during measurement — reveals hidden toxin loads and chronic stress patterns that no blood test can identify. Gabriel is the first health platform to integrate electrodermal organ scoring into a digital health twin, cross-referencing meridian data with wearable biometrics and lab results.
Electrodermal screening reveals organ-level stress patterns that blood work, imaging, and even genetic testing simply cannot see. In clinical studies, EAV achieved 85% diagnostic accuracy matching clinical and radiological findings, detected lung carcinoma in blind tests, and found 27% more dental pathology than X-rays. When we layer this data onto your Health Twin alongside NRT and Bio-Well readings, we get a triangulated view of each organ — three independent systems pointing at the same truth. No other platform in the world offers this.
You'll visit a naturopathic doctor, chiropractor, or integrative practitioner who has an electrodermal screening device in their clinic. The practitioner places a small probe on specific acupuncture points on your hands and feet — each measurement takes 2–5 seconds, with a full assessment covering 40–60 points in 30–45 minutes. The process is painless. Results are immediate and displayed as numerical scores per organ system. Ask your practitioner for a CSV or PDF export to upload to Gabriel.
Conventional practitioners read these results through a disease-focused lens — looking for what's broken. Gabriel reads them through a holistic lens — looking for what's out of balance and how to restore it. We see optimal ranges, not just "normal" ranges. We connect findings across all your diagnostics to reveal patterns that siloed specialists miss.
Electrodermal screening measures electrical conductivity at acupuncture points on your hands and feet. Developed by Dr. Reinhold Voll in the 1950s, it maps energy flow through your meridian system. Readings around 50 indicate balance. Higher readings suggest inflammation or toxicity. Lower readings indicate degeneration or sluggish function.
No. EAV uses the same meridian points as acupuncture but measures electrical resistance rather than inserting needles. It's a diagnostic assessment, not a treatment. The device applies a very weak electrical current (imperceptible to most people) to gather data about your meridian energy flow.
Practitioners use EAV to screen for viral, bacterial, and parasitic infections, environmental toxin load, food sensitivities, vitamin and mineral imbalances, and emotional stress patterns. It can also assess dental health connections (like cavitations affecting meridians) and test remedy compatibility.
EAV devices are not FDA-approved for medical diagnosis. They're classified as bioenergetic assessment tools used in complementary and alternative medicine. Results should be interpreted alongside conventional testing, not as a replacement for it.
No. You hold a metal cylinder in one hand while the practitioner touches a small probe to acupuncture points on your other hand and feet. Most people feel nothing at all. The entire assessment takes 30-60 minutes.
