wo macht man allergietest — which blood markers matter?

Allergy tests are typically done by a dermatologist or allergist. The key blood markers are specific IgE against individual allergens (e.g., pollen, dust mites, foods) and total IgE. Elevated total IgE suggests an allergic tendency but is nonspecific. Specific IgE helps identify triggers. Important: a positive blood test alone does not prove allergy – it must be correlated with symptoms and possibly a provocation test. DNA-based allergy tests (e.g., gene variants) are not clinically established and are not recommended. Evidence for IgE-based blood tests is strong (human-strong), but they do not replace medical diagnosis. Safety note: in case of severe allergic reactions (anaphylaxis), always carry an emergency kit and consult a doctor.
