[How to diagnose food allergy or the importance of the underestimation of food allergy].
Food allergy has an origin of extra-digestive and/or digestive origin. Diagnosis includes the measurements of total and specific IgE, but especially an elimination test for at least a month, followed by re-introduction of the foods. Finally, the assistance is needed of a provocation test against placebo, under control of mediators of anaphylaxis, plasma histamine, tryptase, urinary methyl histamine. Treatment should include, apart from substitution of the food where necessary, the possibility of acceptance of the food under sodium cromoglycate (Nalcron 100 mg or Intercron 100 mg). This development is very desirable. Depending on the subject, and in a time that is difficult to evaluate, there may develop an immunological tolerance to the food.
