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

Allergy tests are typically IgE antibody blood tests or skin prick tests. You can get them done by an allergologist, GP, or in specialized labs; home test kits (e.g., from mybody®x) are also available, analyzing a blood sample. A DNA test, however, cannot diagnose an acute allergy. It may show genetic predispositions for atopy or certain immune responses (e.g., via variants in IL1B, FUT2, or MTHFR), but the association is weak and insufficient to confirm or rule out an allergy. The evidence for DNA-based allergy prediction is mechanistic or unclear – clinical guidelines still recommend IgE testing. If you suspect a specific allergy, a specific IgE test is the gold standard. A DNA test can provide complementary risk hints but does not replace a medical diagnosis. Ensure that home allergy tests (IgE) are validated and that sample collection is correct.
