Annals of Otology, Rhinology & LaryngologyPediatric Allergy Testing: At What Age Is It Worth It?

✅ Clinical Decision Support / Validated Tool

Researchers reviewed serum specific IgE testing results from 606 children with allergic rhinitis symptoms and found markedly higher rates of negative testing before age 3. Concordance between symptoms and allergen sensitization increased as children aged.

Clinical Considerations

• Children younger than 3 years had 15-fold higher odds of negative allergy testing than older children.
• 93.6% of children tested before age 3 had negative results compared with 49.0% of older children.
• Among patients with positive testing, odds of poly-sensitization increased with advancing age.
• Single-center retrospective findings support age-related differences in diagnostic yield but require confirmation in broader populations.

Practice Applications

• Consider age when evaluating suspected allergic rhinitis and planning testing strategies.
• Recognize that negative testing may be common in symptomatic children younger than 3 years.
• Interpret positive sensitization patterns within the context of symptom history.
• Monitor emerging evidence refining pediatric allergy testing thresholds.
