was kostet allergietest — can a DNA test help?

The cost of a standard allergy test (e.g., skin prick test or specific IgE blood test) typically ranges from €50 to €200, depending on the number of allergens and provider. Some direct-to-consumer companies offer DNA tests claiming to predict allergies, but these are not clinically validated for diagnosis. Genetics do influence allergy risk (e.g., HLA, IL-4, FCER1A variants), but effect sizes are small and predictive accuracy for individual allergens is low. Current clinical guidelines still require specific IgE detection or provocation testing to confirm an allergy. DNA tests can at best provide a weak risk indication, not a diagnosis. If you suspect an allergy, consult an allergist for proper testing. Costs are often covered by health insurance if medically indicated. Commercial DNA allergy tests are largely marketing-driven and lack robust evidence.
