I don't know if the SCIO/QXCI machines give a print out after the session is done (?) I'd like to know if they do, but I've never had a session with one of them.
The Biomeridian computer testing I had done for food sensitivites and to pinpoint what was going on in the liver has a print out like you are talking about...green for balanced..red for stressed. Was it done with you holding a handle thing in one hand, and the practitioner touching specific acupuncture points with a small electric rod? And it showed up on the computer right away for whatever specific thing was being tested?
I haven't had him run the parasite program yet, but he told me the biofeedback would go hand in hand with the Rife machine, so I probably will still have him do that too. It's pretty interesting to see what foods I am most sensitive too.
