Oral food challenges (OFCs) are becoming more important because of the move toward early food introduction, as well as the practice of offering low-dose OFCs to infants before starting daily ingestion of a small amount of food protein.1 Both approaches aim to promote and accelerate the development of oral tolerance in infants and toddlers.2 Our previous study revealed that the median times of onset of allergic symptoms following single-dose milk and egg challenges were 20 and 50 minutes, respectively.
