wo macht man allergietest — what can you do yourself?

Allergy tests are typically performed by a doctor (allergist, dermatologist) – e.g., skin prick test or blood test for specific IgE antibodies. Self-tests from pharmacies or online (e.g., IgG food sensitivity tests) are generally not evidence-based and may lead to unnecessary diets or misdiagnosis. DNA tests for single variants (e.g., HLA) are also insufficient for diagnosis. The best approach: document symptoms, consult a specialist, and use validated tests. Evidence: practice/expert opinion. Caveat: Do not self-treat severe allergic reactions.
