The researchers recommend that these children maintain tolerance by consuming peanut products at least once a month.
Researchers recommend performing oral food challenges on children with at least a 50-50 chance of passing, based on IgE antibody levels less than 2.0 kilounits per liter of blood. This guideline aims to reduce unnecessary avoidance of common allergenic foods and improve the accuracy of food allergy diagnosis.
