wo macht man allergietest — what does this mean exactly?

The question 'Where to get an allergy test?' typically contrasts reliable medical testing with commercial home tests. A standard allergy test is performed by an allergist or dermatologist using skin prick tests or specific IgE blood tests. These methods are evidence-based and standardized for diagnosing type I allergies (e.g., pollen, pet dander, foods). Home tests, especially IgG-based food sensitivity tests, are not suitable for allergy diagnosis. IgG antibodies merely indicate exposure, not allergy. Using such tests can lead to unnecessary dietary restrictions or false reassurance. For children, caution is essential: a pediatric allergist should be consulted before any testing or dietary changes. DNA tests for allergies also lack clinical evidence; they analyze small-effect SNPs that do not predict allergic reactions. In summary, a reliable allergy test is performed by a specialist using validated methods. Home tests (IgG, DNA) are not recommended and can be misleading.
