Local allergic rhinitis is a type of allergy that affects the nose and sinuses. It is caused by exposure to allergens such as pollen, dust mites, animal dander, and mold. Diagnosis of local allergic rhinitis involves a physical examination and a detailed medical history.
Physical Examination
During a physical examination, a doctor will examine the nose and sinuses for signs of inflammation. The doctor may also use a stethoscope to listen for any sounds that could indicate an infection or inflammation.
Medical History
The doctor will ask questions about the patient's symptoms, such as when the symptoms began, how long they last, and what activities seem to make the symptoms worse. The doctor will also ask about any allergies the patient might have, as well as any medications or treatments the patient has tried.
Allergy Testing
The doctor may order allergy testing to determine which allergens are triggering the local allergic rhinitis. Commonly used tests include skin prick tests and blood tests. In skin prick tests, a sample of the allergen is placed on the skin and a needle is used to prick the skin and introduce the allergen. If the patient is allergic to the allergen, a reaction will appear on the skin. In blood tests, a sample of the patient's blood is tested for the presence of antibodies to the allergens.
Imaging Tests
In some cases, the doctor may order imaging tests such as X-rays or CT scans to look for signs of inflammation or infection.
Nasal Endoscopy
A nasal endoscopy is a procedure in which a thin, flexible tube with a camera is inserted into the nose to examine the nasal passages and sinuses. This allows the doctor to look for signs of inflammation or infection.
