What it is

Electrodermal testing (EDT) is a family of devices that pass a small current through the skin, usually between a hand-held electrode and a probe pressed on points the method maps to acupuncture meridians, and read the skin's electrical resistance or conductance. Practitioners hold that these…

Format

• The session: the client holds a metal electrode (in EAV, a brass cylinder, sometimes wrapped in moist gauze) and the operator presses a probe on points of the other hand or a foot; a reading, bar or sound appears; for AcuGraph, shoes and socks off and a probe touches each point for a few minutes.…
• The result: a list of "stressed" organs or meridians, "allergies", "intolerances", "toxins", "parasites", deficiencies or remedies; often a product plan follows (homeopathics most often, supplements, diet changes, further sessions, sometimes a home device).

Who practises it, and how they are trained or regulated

• Who offers it: physicians and dentists in some countries, naturopaths, homeopaths, chiropractors, acupuncturists, nutrition and "wellness" practitioners, and unlicensed operators, some with a few days' training or mail-order certificates.
• Training routes as published. The Vienna course is a short continuing-education unit for physicians with basic acupuncture training, with a note that reliable technique takes several days of practice; other routes include device-maker training and operator certificates.
• Electrodermal testing (EDT) is a family of devices that pass a small current through the skin, usually between a hand-held electrode and a probe pressed on points the method maps to acupuncture meridians, and read the skin's electrical resistance or conductance. Practitioners hold that these readings reflect the state of organs, meridians or the body's "regulation", and some versions hold that bringing a substance…

Evidence status, as the guide reports it

• Evidence status (one line). In a double-blind randomised study against skin-prick tests, electrodermal (Vega) testing could not distinguish allergic from non-allergic people, and the authors concluded it "cannot be used to diagnose environmental allergies".

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve any substance, plant preparation, remedy or supplement? Has your doctor or prescriber been told, especially about any medication you take?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• Conflicts of interest and multiple relationships. Working: clear separation, documented.
• Fear of the practitioner, loyalty, shame. Working: the client makes an informed choice about reporting.
• Your own pull to persuade (a rupture risk); pressure from the practitioner or a group. Working: the client makes a decision they can explain in their own values.
• Reported deaths have involved untreated leukaemia and cancer during reliance on EPFX sessions, and an HIV case falsely declared cured. Working: an appointment is made and kept.
• Feeling corrected or shamed (return to 4.2); arguing (do not debate meridian theory). Working: the client can hold both their experience and the information and wants a medical check.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
