Electrodermal Testing - BC Vibrant Health

Electrodermal Testing Electrodermal testing is used to conduct a comprehensive evaluation of a person's energetic health and balance. This process involves measuring electrical conductivity at responsive points (meridian points) on the skin – typically on the hands and feet. The locations of the test points generally correspond to those of acupuncture points.
