Quels sont les examens complémentaires à  réaliser en allergologie pédiatrique ?

The diagnostic of respiratory allergy is done by the concordance of clinical history and the positivity of the skin prick testing. Blood sample is not essential but must be done before specific immunotherapy. In IgE food allergy, positivity of skin prick testing and specific IgE allows to make the diagnostic of allergic sensitisation. The diagnostic of food allergy is done by the positivity of the oral food challenge. In mixed IgE and cell-mediated food allergy, it is necessary to do skin prick testing and atopy patch testing with the food usually ingested by the child. If these tests are positive, they are pertinent when the food eviction improves the clinical symptoms. The release of the symptoms during the oral food challenge will confirm the diagnostic of food allergy.
