wo macht man einen allergietest — can a DNA test help?

Allergy tests are typically performed by allergists or dermatologists, either as skin prick tests or blood tests for specific IgE antibodies. A DNA test (e.g., from MyBody-X) cannot diagnose an active allergy; it can only indicate genetic predispositions for certain allergic conditions or immune responses. The predictive power is limited: most allergies arise from environmental triggers, epigenetics, and exposure history, not just genetics. A positive genetic risk score does not mean you will have an allergic reaction. For reliable diagnosis and treatment, a medical consultation is essential. The evidence for DNA-based allergy prediction is weak to moderate (mechanistic, some GWAS). Without clinical confirmation, dietary or medication changes based solely on a genetic test are not recommended.
