was kostet ein allergietest — can a DNA test help?

The question about the cost of an allergy test and whether a DNA test can help cannot be directly answered from the provided context, as it contains no information on allergy testing. Generally, a clinical allergy test (e.g., skin prick or specific IgE blood test) costs between €50 and €300, often covered by insurance if medically indicated. DNA tests can analyze genetic variants (e.g., HLA, IL-4) linked to allergy risk, but the evidence is weak: most markers have small effect sizes and are not diagnostic. A DNA test may offer additional context but cannot replace clinical testing. Costs for consumer DNA tests range from €100 to €300, rarely reimbursed. For reliable diagnosis, consult a doctor. Evidence: unclear/marketing.
