Lay opinion vs evidence: IgE Allergie Check

An IgE allergy check measures specific IgE antibodies to allergens. The evidence is mixed: IgE tests are clinically established for diagnosing allergies (e.g., seasonal allergies), but many consumer home tests lack validation in controlled trials. Lay opinions often interpret a positive result as a definite allergy, whereas a positive IgE often indicates sensitization, not necessarily clinical allergy. False-positive rates are high, and interpretation requires medical expertise. Without history and challenge tests, the result may lead to unnecessary dietary restrictions or anxiety. Evidence: human-moderate (for clinical tests), marketing/unclear (for home tests).
