wo kann man allergietest machen — can a DNA test help?

Allergy testing should always be done by a doctor or allergist. Standard methods are skin prick tests and specific IgE blood tests. DNA tests sold directly to consumers cannot diagnose allergies. They often measure IgG antibodies to foods, which is not a valid marker for allergy – IgG indicates exposure, not hypersensitivity. True allergies are IgE-mediated and require clinical evaluation. A DNA test may hint at genetic predispositions (e.g., for hay fever), but it cannot confirm an active allergy. Evidence for such tests is weak to marketing-driven. Do not be misled by personalized 'allergy DNA profiles' – they do not replace medical diagnosis. If you suspect an allergy: see a specialist for proper testing. Safety note: self-tests can lead to unnecessary dietary restrictions or false reassurance.
