was kostet ein allergietest beim arzt — what are common causes?

The cost of an allergy test at a doctor's office depends on the test type (prick test, blood test) and country. In Germany, statutory health insurance usually covers costs only if there is a justified suspicion; private insurance often pays. Common causes include pollen, dust mites, animal dander, mold, foods, and insect stings. The provided context does not contain specific information about allergy tests or causes; it focuses on DNA tests for sleep, weight, and other topics. Therefore, the evidence for this answer is based on general medical knowledge, not the given sources.
