ist ein allergietest kostenlos — which blood markers matter?

Whether an allergy test is free depends on the healthcare system. In Germany, statutory health insurance covers allergy testing (e.g., skin prick test or specific IgE blood test) only if there is a justified suspicion of allergy—such as recurrent sneezing, rash, or breathing difficulties. Without medical indication, patients pay out-of-pocket (approx. €50–150). Over-the-counter or online self-pay tests are usually not reimbursed. Which blood markers matter: Specific IgE (sIgE) against individual allergens (e.g., grass, birch, dust mite) is the gold standard. Total IgE may be elevated but is nonspecific. Eosinophil count in the CBC can hint at allergic reaction but is not diagnostic. Tryptase is measured if anaphylaxis is suspected. Important: A positive IgE alone does not confirm allergy—only the combination with symptoms and possibly provocation tests establishes the diagnosis. Direct-to-consumer DNA tests (e.g., for gene variants) are not suitable for allergy diagnosis because they show risk tendencies, not current sensitizations. Evidence: clinical practice guidelines (e.g., AWMF).
