peanut 5 (21%), egg 3 (13%), fish 1 (4%) and fruits 1 (4%). Peanut could be reintroduced to all children after CRD, egg and milk after specific IgE IVD. Prior to the introduction of food a secondary care specialist food provocation was performed to confirm the IVD result. ConClusions: CRD ISAC was beneficial in 54% of the cases and in 21% of the cases it was critical for decision making. The aim of the study was reached as avoidance diets decreased by 63%. The results indicate, even with low patient recruitment, it is likely that introducing ISAC IVD to traditional diagnostic algorithm can be considered cost-effective, with an average cost per avoided unnecessary diet for 480 EURs per child. To confirm the findings a larger study will be executed.
