wo kann ich einen allergietest machen — what can you do yourself?

The question 'where can I get an allergy test and what can I do yourself?' is common, but it's important to distinguish between self-management and medical diagnosis. On your own, you can keep a detailed symptom diary: note timing, foods, pollen counts, or animal exposure. An elimination diet (e.g., removing dairy, wheat, nuts for 2–4 weeks) may provide clues, but should be guided by a professional to avoid nutritional deficiencies. Over-the-counter IgE finger-prick tests sold online or in pharmacies have high false-positive rates and are not recommended by allergists. Consumer DNA tests (e.g., for FCER1A or HLA variants) are not validated for allergy diagnosis – they indicate genetic predisposition, not current allergic disease. The only reliable self-help is careful observation and avoidance of suspected triggers. For a definitive diagnosis (skin prick test, specific IgE blood test, oral food challenge), you must see a doctor or allergist. Evidence for self-tests is weak; clinical practice relies on standardized procedures. Safety note: If you have ever experienced severe reactions (anaphylaxis), never self-test; create an emergency plan with your physician.
