ist ein allergietest kostenlos — can a microbiome test help?

Whether an allergy test is free depends on the type and medical necessity. IgE tests (skin prick or blood) for classic immediate-type allergies are typically covered by public health insurance in Germany if prescribed by a doctor for a suspected allergy. In contrast, IgG food tests are not recommended by major allergy societies (EAACI, AAAAI, DGAKI) because they reflect food exposure, not intolerance or allergy; these tests are usually paid out-of-pocket and can lead to unnecessary dietary restrictions. As for microbiome testing: while the gut microbiota may influence immune function and allergic diseases, current evidence does not support using microbiome tests to diagnose or manage allergies. Guidelines consider them experimental for this purpose. If you suspect an allergy, consult a physician for a validated IgE test – that is often free. Microbiome tests are generally not covered and should not replace medical evaluation.
