What is ElectroDermal Screening?

EDS measures the resistance to the flow of electrons through the body. Since many factors cause the body's resistance to change, EDS identifies these factors.

What am I tested for?

The technology tests the overall functionality of your organs and systems, in addition to the presence of dangerous bacteria, viruses, fungus, allergens, emotional stress, metals like lead and mercury, chlorine, pesticides, chemicals, and vitamin/mineral deficiencies. Homeopathic liquids, supplements and medications can also be tested with the patient.

What happens during an appointment?

You will hold the brass electrode (pictured right), the source of the minute electrical current. Then, with another electrode (pictured left), I will gently touch the skin above your fingernails. Then, data is captured from the intensity of the electrical current.

Is it FDA-approved?

The Discovery System is recognized by the FDA as an investigational device. Computerized biofeedback analysis is endorsed by many doctors here in the US, including Dr. C. Shang of Harvard University who has urged the medical community to make full use of this technology in order to gain knowledge of the body’s functions. Today, this technique is used in the most progressive institutions in countries throughout the world: Germany, France, England, South America, China, Canada, Australia, and the United States.


To begin with, founder Laura Notorangelo's life was saved through electrodermal testing. It's how she found Borrelia burgdorferi (the catalyst of Lyme disease).

Testing can find the cause(s) of the following symptoms, because it conducts a dynamic assessment of the body's tissues, organs and systems:

  • Allergies
  • Sleep problems

  • Brain fog (i.e. confusion, forgetfulness or lack of focus)

  • Weight problems

  • Fatigue

  • Headaches

  • Joint discomfort 

  • Muscle discomfort

  • Recurring infections

  • Stress

  • Mood swings

  • Digestion issues


The Discovery system, a state-of-the-art testing device with Windows software that translates the results instantly. It measures electrical currents in the body, like an Electrocardiogram (ECG or EKG) machine measures the electrical activity of the heart.


EDS has its earliest roots in galvanic skin testing. The galvanic skin response, a method of measuring the electrical resistance of the skin, was discovered in the early 1900s.

In the 1950s, a West German physician and acupuncturist named Reinhold Voll combined acupuncture theory with galvanic skin response technology. He tested the skin along various points with particular attention to the acupuncture meridians. This is how galvanic skin response testing became known as EDS. Galvanic skin response changes are still used in lie detector tests, along with several other measures such as pulse, breathing, and blood pressure.

Disclaimer: (EDS) energetic values are used as a complementary tool along with traditional standards of care and diagnostic guidelines established by the AMA and AOA. At this time, the use of (EDS) in the United States is not intended for the purpose of medical diagnosis but can be used to interface patient frequency with treatment frequency.
