was kostet allergietest — what can you do yourself?

The cost of an allergy test from MyBody-X is not explicitly stated in the provided context, but typical prices for blood intolerance tests range from €50–150. Importantly, these tests are not diagnostic and under German law (GenDG) cannot replace a medical diagnosis. What you can do yourself: Keep a food diary, try an elimination diet (e.g., avoid common allergens like dairy, gluten, nuts for 4 weeks) and track symptoms. IgG blood tests for food intolerances are considered insufficiently evidence-based by medical guidelines. If you suspect a true allergy (e.g., hives, breathing difficulty), see a doctor. A DNA test for genetic predispositions (e.g., lactose intolerance) can give hints but not a diagnosis. The evidence for such self-tests is weak to moderate. Bottom line: Don't skip medical evaluation, but self-observation can be a useful first step.
