was kostet ein allergietest — what symptoms are typical?

The provided context does not contain specific information about allergy test costs or typical symptoms. The knowledge base covers DNA tests for sleep, nutrition, vitamin D, and collagen, not allergy diagnostics. In general, allergy tests (skin prick, specific IgE blood tests) cost between 30–150 EUR in Germany, often not covered by insurance. Typical symptoms include sneezing, itching, hives, respiratory distress, or gastrointestinal issues, depending on the allergen (pollen, food, insects). Evidence for direct-to-consumer allergy tests is weak; official guidelines recommend physician-led diagnosis. Without relevant sources, the answer remains conservative and evidence-aware. Safety note: Suspected severe allergies (anaphylaxis) require immediate medical attention.
