AbstractsResults OFC was performed in 52 neonates and positive inductions of symptoms were seen in 23 (44%) of the challenged neonates. The majority had mild digestive symptoms which disappeared immediately after elimination of the causal milk. According to the results of OFC, the sensitivity, specificity, and positive predictive value of milk-specific IgE were 0%, 93%, and 0%, and those of the allergen-specific lymphocyte stimulation test were 61%, 76%, and 67%, respectively. Conclusions Diagnostic OFCs for CMA were safely carried out in neonates. The discontinuation of certain foods as part of an elimination diet can lead to appropriate nutrition management. In NICUs, OFC should be carried out more aggressively with careful observation.
