wo kann ich einen allergietest machen — what are common causes?

The provided context does not specifically address allergy testing or common causes. The articles focus on DNA tests for metabolism, nutrition, longevity, and microbiome, not allergy diagnostics. In general medical practice, allergy tests are performed by allergists via skin prick tests, specific IgE blood tests, or challenge tests. Common triggers include pollen, dust mites, pet dander, mold, foods (e.g., peanuts, milk, eggs), and insect venom. MyBody-X offers intolerance tests (e.g., lactose, fructose), which are not classical allergy tests. Evidence for genetic allergy predisposition is moderate (GWAS), but a DNA test cannot replace clinical allergy diagnosis. If an allergy is suspected, consulting a doctor is the first step.
