Abstract BACKGROUND: Oral food challenges remain the gold standard for the diagnosis of food allergy. However, clear clinical and laboratory guidelines have not been firmly established to determine when oral challenges should be performed. OBJECTIVE: We sought to determine the value of food-specific IgE levels in predicting challenge outcome. METHODS: A retrospective chart review of 604 food challenges in 391 children was performed. All children had food-specific IgE levels measured by means of CAP-RAST before challenge. Data were analyzed to determine the relationship between food-specific IgE levels and challenge outcome, as well as the relationship between other clinical parameters and challenge outcome. RESULTS: Forty-five percent of milk challenges were passed compared with 57\% for egg, 59\% for peanut, 67\% for wheat, and 72\% for soy. Specific IgE levels were higher among patients who failed challenges than among those who passed (P
