Diagnosis is based upon a thorough history and physical examination from a healthcare provider. To confirm a diagnosis, nasal corticosteroids may be prescribed to see if there is a reduction in symptoms. In some cases, blood tests measuring allergy sensitivity or skin prick testing (a procedure where a small amount of the allergen is exposed to the skin) are also used. Rarely, imaging can be used, such as a CT scan, but this is typically not necessary.[1]
