Australian Study Finds One-Third of Infants Misdiagnosed with Peanut Allergy

Australian researchers in Melbourne reported that about one-third of infants who had tested positive for peanut allergy tolerated peanuts during supervised oral food challenges, prompting calls for routine retesting. Earlier national research involving the Murdoch Children’s Research Institute and the National Allergy Centre of Excellence had shown that roughly 35 % of infants under 18 months previously diagnosed did not react in supervised challenges, suggesting over-diagnosis and the need for confirmatory testing before long-term treatment.
