Food intolerance

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 IgE

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 food intolerance.

Measurement of total IgE will permit the ratio of specific to total IgE to be assessed in positive samples.
