Allergic rhinitis is a relatively common otolaryngological disease. The main cause is the body's immune response triggered by contact with allergens, leading to an imbalance in the immune status and causing a series of clinical symptoms. Therefore, in terms of treatment, it is first necessary to identify the specific types of allergens. Currently, there are two methods for allergen testing. The first method is ex vivo allergen screening, which involves blood tests. The second method is the skin prick test to identify specific allergens. Both methods are commonly used at present, and generally, choosing one of them is sufficient. However, a subset of patients may need a combination of both tests for a comprehensive assessment.
