When I was examined by the QXCI machine, the practitioner had to input what diseases and/or symptoms I was suffering from prior to scanning me with the machine. It finds out why the person is having those symptoms. For instance, if 5 people are all suffering from the same symptom, ie. diarrhea, the machine may detect that in one person the cause is a virus, in another it's emotional, and in the three other it is caused by bacteria. Even though everyone exhibits the same symptoms, the cause is different, and this warrents different treatments. It also taps into the unconsciousness.
Hope this helps... U may refrain from telling the practioner that your wife suffers from colitis, as a means of seeing if the machine will detect it, but I see no benefit to doing this.
