Thanks guys for replying,

"What is Electro Dermal Screening. CEDS (computerized electro dermal
screening), sometimes called bio-energetic testing, has been in use world wide
since the early 1970's. It is a safe and noninvasive screening technique that
measures the ability of the body to transmit a milliamp of current through various
acupuncture meridians. The value of the current is so low that it produces no physical
sensation Based on the measured resistance, we can make assessments on the
balance of the system. Each individual acupuncture point can provide specific data
which can help identify the source of the problem far beyond simply identifying the
symptoms. After determining the nature of an imbalance, we then attempt to create a
positive response utilizing herbal, nutritional, or homeopathic remedies. Once
balance is restored to the body, most clients experience a renewed sense of
wellness and a return to good health."

I have a fairly open mind and I do believe in acupuncture and the energy systems of the body. But how can we be sure that a machine like this actually measures anything useful? I'm not convinced so I'll keep trying to find someone here that does serum testing. So far no luck with that <img src="/ubbthreads/images/graemlins/frown.gif" alt="" /> I'm trying to do all the right things which while frustrating, I guess will pay off in the end!
