This is via a lancet prick, sample and sent by mail for evaluation.
Research in the Alternative Medical Review Journal, compared this evaluation with various other food tests and found it to be 100% specific. Clinically, this evaluation is proven to be very accurate at finding foods that cause symptoms in the body.
This evaluation reports foods that are not digested well and therefore these foods would create toxic build up and this can lead to digestive issues, bowel issues, immune problems, including creation of allergies, eczema, recurrent ear throat bladder and most other infections, chronic inflammation, headaches, etc.
This evaluation is highly recommended for infants, before food introduction occurs, but is great for all ages.
