wo kann man einen allergietest machen — what can you do yourself?

You can get an allergy test from your GP, an allergist (skin prick test, specific IgE blood test), or via direct-to-consumer providers like myBody-X (food allergy blood tests). What you can do yourself: keep a symptom diary, note potential triggers, and try an elimination diet under medical supervision. Caveat: home tests often have weak evidence, measure IgG sensitivities (not true allergies), and may lead to unnecessary dietary restrictions. For suspected true allergies (anaphylaxis, hives, swelling), see a doctor immediately. The evidence for at-home allergy tests is limited – validated methods remain clinical (skin prick, IgE). Self-help is useful for tracking but not for diagnosis.
