Myths vs facts: AllergieCheck | IgE-Antikörper Test and gut health

The AllergieCheck (IgE antibody test) measures specific IgE antibodies to foods or inhalants. A positive IgE result indicates sensitization, not necessarily clinical allergy. The link to gut health is indirect: impaired gut barrier ('leaky gut') may promote sensitization, but IgE tests are not direct markers of gut flora or function. Many providers market such tests as 'allergy checks' implying comprehensive diagnostics, yet evidence for standalone interpretation without medical history is weak. Studies show up to 50 % of positive IgE findings are clinically irrelevant. For gut health, stool tests (microbiome, calprotectin) or specific IgG tests (controversial) are more relevant, but standardized norms are often lacking. Bottom line: IgE testing can be useful when true allergy is suspected, but not as a sole indicator for gut issues. Seek medical advice before acting on results.
