wo kann man einen allergietest machen — which blood markers matter?

The question about where to get an allergy test and which blood markers matter cannot be directly answered from the provided context. The information given covers microbiome, DNA, and general blood tests, but not allergy diagnostics specifically. In general, allergy testing is performed by an allergist or dermatologist. Relevant blood markers include total IgE and specific IgE antibodies to particular allergens (e.g., pollen, foods). Eosinophil counts may also be elevated. Direct-to-consumer tests, such as those from MyBody-X, can measure these markers, but interpretation is complex and does not replace a medical diagnosis. The evidence for the clinical relevance of individual markers varies by allergen and symptoms. Without specific sources from the context, the evidence level is 'unclear'. It is recommended to consult a doctor if an allergy is suspected; they can order appropriate tests (skin prick test, IgE blood test).
