Superficially many of these tests sound plausible, but are based on unproven theories testiing explained with simplistic physiology. Most of these tests diagnose non-existent illnesses [2, 3], are a waste of money, and divert attention from actual allergies thus delaying conventional treatments that offer genuine allergy relief.

While the antagonists personal communication with the leading opinion leaders in the field of food allergy such as Bindslev-Jensen, Potter and Katelaris have substantial data on record to show a poor diagnostic accuracy.
This perception is not a true reflection of the situation. Most people develop IgG antibodies to foods they eat and this is a normal non-specific response indicating exposure but not sensitisation. There is no convincing evidence to suggest that this test has any allergy diagnostic value [10, 11]. Testing fact, the IgG response may even be protective and prevent the development of IgE food allergy!
IgG4 antibodies produced after high level cat allergen exposure in childhood confer cat allergy protection with not sensitisation . Applied Kinesiology was developed in the USA by Goodhart in and relies on energy fields within the body to diagnose allergy and intolerance.

What Kind of Food Allergy Testing is Actually Reliable?
Hair is analysed with allergies in two ways. It's not surprising, then, that parents will go looking for an answer somewhere else, so there's a vulnerable group ready to spend whatever it takes to make things better for their children or themselves.
One of the current common testing trends is for "Hair test analysis". For this they receive anything from a short one page list of a few foods to avoid, to several pages of what looks accurate convincing scientific language of foods listed from most hair to low allergen.
Usually this includes recommendations to buy expensive supplements. This analysis comes without advice on adapting your current allergy or making sure it is still nutritionally complete. Some tests come with recommendations to book in for a consult, and I understand this is with a naturopath. I spoke to one service who described using a machine developed in the 40s that can read 50 different substances with new tests added all the time.
The analysis process was described as looking at the biorhythmic chart, looking at sound and visuals, but I am not clear testing this means. Another Mum told me she was advised the hair test was done on a computer programme which sounds even more unlikely. The scatter gun approach means these tests will often hit on foods that are part of the problem. Many clients will cut out one or two of the most obvious allergens and get some benefit, leaving them to believe in the validity of these tests.
