This section deals with the clinical condition food intolerance,
listing the relevant immunological tests, together with a short
explanation of their use.
Relevant immunological tests: IgE and Allergen Specific
Evidence of specific IgE antibodies may be consistent with a
diagnosis of food allergy but, unfortunately, the presence of such
antibodies does not prove clinical sensitivity.
Elimination and food challenge testing may help confirm or rule
out food intolerances.
Laboratory immunology tests cannot help investigate non-allergic
Measurement of total IgE will permit the ratio of specific to
total IgE to be assessed in positive samples.
