was kostet allergietest — what does this mean exactly?

The question about the cost of an allergy test at MyBody-X cannot be answered from the provided context – there are no prices or product descriptions for allergy tests. MyBody-X primarily offers microbiome, metabolism, and DNA tests, typically priced between €100 and €300, but this is unverified. An allergy test can take different forms: classic IgE tests (medical, often covered by insurance) or IgG food sensitivity tests, which are scientifically controversial. MyBody-X might offer such a test, but without concrete sources this remains speculation. Importantly, a positive IgG result does not indicate a classic allergy but often just an immune reaction to commonly eaten foods. The evidence for the utility of such tests is weak. If you are considering an allergy test, consult an allergist instead. The cost question can only be answered by noting the lack of data and the need for medical clarification.
