Diagnostic Testing in the Evaluation of Food Allergy

초록

Food-related symptoms are frequent in childhood, and pediatricians are often requested to initiate a food allergy diagnostic workup. A careful history is the cornerstone for assessing whether tests are needed and which diagnostic procedures are most appropriate. Skin prick tests should be performed only according to standard procedures by a skilled health professional. Determining serum IgE levels (in vitro tests) are available for a wide range of foods. Of utmost importance is the need to correlate test results to the clinical picture. When a conclusion cannot be reached, oral food challenges should be performed for a definite diagnosis.
