What to watch with IgE Allergietest and Darmgesundheit?

When combining an IgE allergy test with gut health assessment, caution is warranted: elevated IgE indicates allergic sensitization but does not directly reflect gut microbiota composition. The gut-brain axis and microbiome studies show associations with allergic diseases (e.g., eczema), but evidence is mostly observational. Home IgE tests can yield false positives or clinically irrelevant results. A microbiome test may offer dietary guidance but cannot diagnose allergies. Evidence for directly modulating allergies via gut health is moderate. Caveat: IgE results must be interpreted with symptoms and clinical history. Do not self-treat based on these tests alone.
