Is Mikrobiom Test useful for allergy?

Whether a microbiome test is useful for allergies is not clearly supported by current evidence. While the gut microbiome can influence immune responses and allergic conditions via the gut-immune axis, commercial at-home tests (e.g., MyBody-X Darm Mikrobiom-Test) lack validated biomarkers or clinical utility for allergy diagnosis or management. The test's specific biomarkers for allergy are not described, and the evidence grade is unclear. In contrast, IgE blood tests (also offered by MyBody-X) indicate sensitization but not allergy – many sensitized individuals tolerate allergens. For genuine allergy concerns, clinical history and specialist evaluation are essential. Relying solely on a microbiome test for allergy decisions is not recommended. Evidence level: unclear/marketing. Safety note: Do not use test results to self-diagnose or alter treatment without medical guidance.
