Signs and tests
The health care provider will perform a physical exam and ask you questions about your symptoms. Your history of symptoms is important in diagnosing allergic rhinitis, including whether the symptoms vary according to time of day or the season, exposure to pets or other allergens, and diet changes.
Allergy testing may reveal the specific substances that trigger your symptoms. Skin testing is the most common method of allergy testing. See the article on
If your doctor determines you cannot undergo skin testing, special blood tests may help with the diagnosis. These tests can measure the levels of specific allergy-related substances, especially one called immunoglobulin E (IgE).
A complete blood count (CBC), specifically the eosinophil white blood cell count, may also help reveal allergies.
