wo kann man einen allergietest machen — can a microbiome test help?

Allergy testing is medically done via IgE blood tests (RAST/ImmunoCAP) or skin prick tests, ideally by an allergologist or GP. A microbiome test (e.g., from MyBody-X) cannot diagnose allergies because allergies are an immune reaction to specific proteins, not a direct consequence of gut flora. However, some evidence links gut dysbiosis to allergic conditions like hay fever or eczema – but this is mostly mechanistic/observational, not strong enough for clinical guidance. A microbiome test may provide supportive context but should never replace standard allergy diagnostics. Beware of marketing claims: a stool-based 'allergy test' is not scientifically validated. If you suspect an allergy, see a doctor.
