Please don’t waste your time and money on any allergy “test” that claims they can diagnose allergies using hair, saliva and a biofeedback machine. They are not reliable. Biofeedback has only been approved to help control body functions such as stress and pain. They cannot diagnose or cure any conditions. Check out this Mayo Clinic link:

There are tons of other sites that confirm this information. Check it out!
