Allergic rhinitis can be screened for allergens. Currently, allergy testing is mainly conducted through two methods. The first method is blood testing, and the second method is a skin prick test. Blood testing is more commonly used and typically involves various allergens, such as dust, pollen, pets, hair, and it could also be due to allergies to seafood or mold, plants. Both skin prick tests and blood tests can be used. If one method does not provide sufficiently clear results, both types of allergen tests can be performed simultaneously for a more accurate comparison.
