“Early in my own education in modern quackery, I found it particularly distasteful not merely that quacks misuse laboratory tests, but that several commercial laboratories market misleading tests. To the untrained eye these laboratories appear to be legitimate, even to the point of their being approved by apparently legitimate certifying bodies.”  Kimball Atwood MD, Science Based Medicine (29th April 2010)

"Many unconventional allergy tests are available which purport to diagnose a number of maladies. Tests range from electro dermal tests to trace metal estimation in hair samples. These un-validated tests are sometimes promoted by complementary and alternative medicine (CAM) practitioners. Superficially many of these tests sound plausible, but are based on unproven theories and explained with simplistic physiology. Most of these tests diagnose non-existent illnesses, are a waste of money, and divert attention from actual allergies thus delaying conventional treatments that offer genuine allergy relief.” Dr Adrian Morris, Allergy Clinician (2008)

A well reasoned analysis of about 30 allergy-related tests and treatments that "have been promoted in the absence of any scientific rationale".

Inappropriate testing includes cytotoxic testing (Bryans' test), oral provocation and neutralization, Vega testing (electrodermal testing), kinesiology, radionics (psionic medicine, dowsing), iridology, pulse testing, hair analysis, and tests for "dysbiosis"; Inappropriate use of conventional testing includes food specific IgG, IgG4, IgE, lymphocyte subset analysis, and allergen specific IgE (RAST, ImmunoCap testing);

Inappropriate use of conventional treatments looks at allergen immunotherapy;

Treatments used by conventional and unorthodox practitioners looks at Buteyko Breathing Technique and elimination diets;

Unorthodox treatments include homeopathy, acupuncture, reflexology (zone therapy), autogenous urine therapy, physical therapies (chiropractic, osteopathy, cranial therapy), allergy elimination techniques (also known as 'Advanced Allergy Elimination", and "Nambudripad's Allergy Elimination"), Vega MRT (Matrix Regeneration Therapy), clinical ecology/environmental illness, chronic candidiasis, enzyme potentiated immunotherapy, and insulin resistance/allergy.

A hair sample of a single donor was sent to six different laboratories for hair mineral analysis. Laboratory designations of normal reference ranges varied greatly, resulting in conflicting classifications (high, normal or low) of nearly all minerals analysed. Laboratories also provided conflicting dietary and nutritional supplement recommendations based on their results. Concludes that hair analysis is not reliable. The Journal of the American Medical Association (January 2001)

"Vega testing (the Vega test method) is an unorthodox method of diagnosing allergic and other diseases. It has no established scientific basis and there are no controlled trials to support its usefulness. Vega testing may lead to inappropriate treatment and expense to the patient and community." Position statement of the Scientific and Therapeutic Subcommittee of the Australian College of Allergy. Medical Journal of Australia (1991)
