Is IgE Allergietest useful for Darmgesundheit?

An IgE allergy test is not generally useful for assessing gut health. IgE-mediated reactions are immediate-type allergies (e.g., hives, anaphylaxis) and are rarely the root cause of chronic gut issues like bloating, diarrhea, or abdominal pain. Most food intolerances (lactose, fructose, celiac disease) or irritable bowel syndrome are not IgE-driven. An IgE test may be helpful if specific foods trigger acute allergic symptoms. For comprehensive gut health evaluation, stool tests (microbiome, calprotectin, elastase) or breath tests (lactose, fructose) are more appropriate. The test is not a screening tool for general gut health. Caveat: A negative IgE result does not rule out other gut problems. Evidence: practice/unclear.
