The majority of children diagnosed by skin prick tests as having a sensitisation to peanuts are not allergic to them, according to research.
Of the 91 children in the study who were confirmed to have a sensitivity to peanuts, less than 23% were actually found to have a clinical allergy.
The Ara h 2 allergen found in peanuts was noted as the most critical component to predicting allergy.
The British and Swedish scientists published their findings in the Journal of Allergy and Clinical Immunology. They used a combination of oral food challenge and skin tests to assess the children’s sensitivity.
