allergic rhinitis diagnose

To find out if you have allergies, your doctor will ask about your symptoms and examine you. Knowing what symptoms you have, when you get them, and what makes them worse or better can help your doctor know whether you have allergies or another problem.

If you have severe symptoms, you may need to have allergy tests to find out what you are allergic to.

• Your doctor may do a skin test. In this test your doctor puts a small amount of an allergen into your skin to see if it causes an allergic reaction.
• Your doctor may order lab tests. These tests can find substances in your blood or other fluids that may mean you have allergic rhinitis.
