How is Allergic Rhinitis Diagnosed?

Allergic rhinitis is diagnosed based on a combination of medical history, physical examination, and allergy testing. Allergy testing may involve skin prick tests or blood tests (such as specific IgE tests) to identify specific allergens that trigger allergic symptoms in an individual. Imaging studies such as nasal endoscopy or sinus CT scans may be performed in some cases to evaluate the severity of nasal inflammation or to rule out other underlying conditions.
