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

Allergy tests are typically done by allergologists or dermatologists. The gold standards are skin prick tests and specific IgE blood tests. Over-the-counter home tests (e.g., for pollen or food) are often unreliable and can give false positives/negatives. What you can do yourself: keep a symptom diary, note potential triggers (food, pollen, pet contact), and try eliminating suspected substances for 2–4 weeks. For suspected food allergy, a medically supervised oral food challenge is the gold standard. For dust mite or pollen allergies, use allergen-proof encasings, HEPA filters, and regular ventilation. Self-testing is not recommended for diagnosis; always consult a doctor, especially if you have had severe reactions. Evidence level: practice (common medical practice).
