Reintroduction of foods after a negative oral food challenge – a two year follow up

Oral food challenges (OFCs) are the gold standard in the diagnosis of food-related allergic symptoms and can help determine if a food can be safely reintroduced into the diet.1-3 Following a negative OFC, patients are recommended to regularly consume the food.1,4 While data are limited, there are multiple published cases of recurrence of peanut allergy after a negative OFC when there is infrequent consumption.1,4,5 In 2015 van der Valk et al. found that among a group of Dutch patients, successful reintroduction was as low as 56% due to a number of patients having reactions to the food even after a negative OFC.
