In children at high risk for peanut allergy, what step can be considered before introducing peanut-containing products?

• A. Immediate introduction without testing
• B. Allergy testing
• C. Avoidance entirely
• D. Delaying until age 3

Answer: (B)

Assessing peanut allergy risk with targeted testing helps tailor how to introduce peanut-containing foods in children who are at high risk. In kids with severe eczema or other atopic conditions, there’s a higher chance of developing a peanut allergy, so checking for sensitization before early introduction makes sense. A negative peanut skin prick test or low peanut-specific IgE suggests a low likelihood of a true allergy, so peanut-containing foods can usually be started safely (often at home) with appropriate supervision. If testing is positive or uncertain, referral to an allergist for evaluation is advised; they may arrange a supervised oral food challenge to determine whether the child can tolerate peanut, or provide a careful plan to avoid it if tolerance is not present. This approach helps prevent peanut allergy while avoiding unnecessary avoidance in those who aren’t truly allergic.
