This Elisa test checks 96 common foods against the three main
antibodies: IgA, IgG and IgM, giving the most comprehensive antibody
test I can find. I use this to find the most obvious signs of food
sensitivity. It can then be wise to combine this with the allergen
tests eg ALCAT, LRA or FACT to find both antibody and other immune
reactions. For more on Allergy testing, please read the Allergy Test FAQ
Increased levels of IgG antibodies are an indication of recent food
hypersensitivity. However, I have chosen to add IgA and IgM to IgG
because, in some cases, IgG may not show up - if the immune reaction is
in the mucosal tissues for example. IgA is the first antibody released,
followed by IgM and then IgG when it is systemic.
Here is the info from Alletess lab in the US who do this test for me as
I cannot get it done in the UK:
The Comprehensive Food Sensitivity Panel measures serum concentration
of IgG, IgA, and IgM antibodies specific to 96 foods
• Measurement of food-specific IgG, IgA, and IgM may be useful
in determining whether a food sensitivity is present and, if so, the
antigen(s) causing the sensitivity
• Elevated antibody levels are an indication of food
sensitivities or various gastrointestinal or other disorders
• The assay is highly sensitive, specific and reproducible
• Methodology: Enzyme-linked immunosorbent assay (ELISA)
Please note that the sample needs to be
so you will need to have your blood sample taken at a place where that
can be done - usually an NHS or private hospital (eg. BUPA/Spire or
have walk-in services and normally cost about
£10-£20) or a large GP
surgery. Also, note that this (and all
Alletess antibody tests) must be couriered back to the US
UK Royal Mail no longer allows you to send samples internationally so
do bear extra courier return costs in mind.
The complete list of foods includes specific fruits, vegetables, dairy
products, peanuts, tree nuts, fish, shellfish, meat, herbs and spices
(see list below).
Sensitivity to foods is an abnormal response to a food component
triggered by the immune system in the form of immunoglobulins (IgG, IgA
and IgM), representing
a delayed type hypersensitivity reaction. Food hypersensitivity may be
caused by many factors such as stress, infection, overeating,
artificial preservatives, additives, fungicides, molds, pesticides,
antibiotics, and environmental pollutants.
Among the many organs involved, the skin, gut, and respiratory tract
are most affected by food hypersensitivity reactions. Food
hypersensitivity contributes to many health problems and complaints,
including fatigue, migraine headaches, rhinitis, asthma, recurrent ear
infection, abdominal pain, irritable bowel, rectal itching, bedwetting,
arthralgia, eczema, urticaria, rashes, and anxiety.
Identifying and avoiding foods to which a person is sensitive can solve
many of these problems.
The following conditions may be associated with food sensitivity:
Autistic Spectrum Disorder, Pervasive Developmental Disease
Attention Deficit Disorder
Irritable Bowel Syndrome
Chronic Fatigue Syndrome

allergy tests, if you suspect certain foods, it is
best to have those in your system for an antibody to show up. Obviously
start eating something you already know is a problem and make yourself
steroids (inc creams) or immune suppressant drugs will affect results
so the advice
is to stop those for 48 hours if possible (talk to your health
Long term steroids may affect results.
Please remember this test has to be centrifuged and then couriered back
to the US within a week.
