Costs for IgE-related allergy testing and nutritional management vary widely by country, test scope, and insurance. A basic total IgE blood test typically costs €20–50 in Germany; specific IgE tests for individual allergens range from €10–30 per allergen. Comprehensive panels (e.g., 20–40 foods) can cost €200–500. Public health insurance often covers tests only with a justified clinical suspicion; private insurance depends on the plan. Additional costs include allergist consultations (€50–150) and dietician sessions (€50–100 each). Elimination diets may increase grocery expenses. Evidence: IgE levels indicate sensitization, not necessarily clinical allergy. Many direct-to-consumer labs overstate the predictive value. A positive IgE without symptoms rarely justifies dietary changes. Always correlate with history and, if needed, oral food challenges. Be cautious of marketing that promises quick answers – costs can add up without clear benefit.
