wie teuer ist ein allergietest — which blood markers matter?

The cost of an allergy test varies widely depending on scope (single allergen vs. panel), provider, and country. A basic IgE blood test for common inhalant or food allergens typically ranges from 30 to 150 EUR if self-paid. In Germany, statutory health insurance covers costs only with a justified suspicion and a doctor's order. Key blood markers include specific IgE to individual allergens (e.g., birch, grass, peanut) and total IgE. An elevated level indicates sensitization, not necessarily allergy – false positives are common. IgG tests (e.g., for food intolerances) lack scientific evidence and are discouraged by guidelines. Other markers like hsCRP or eosinophil count may provide hints but are non-specific. Bottom line: an allergy test is only useful with clinical interpretation; home tests cannot replace a specialist diagnosis.
