A new Australian study shows that more than one‑third of infants who test positive for peanut allergy may actually be tolerant. Researchers at the Murdoch Children’s Research Institute and the National Allergy Centre of Excellence found that 34.8 percent of infants who initially tested positive did not react during supervised oral food challenges. The study, published in The Journal of Allergy and Clinical Immunology, suggests that routine oral challenges could prevent unnecessary avoidance diets. Experts advise parents to discuss retesting with an allergist, as home challenges can trigger severe reactions. The findings highlight the need for updated testing protocols in pediatric allergy care.
