Your doctor or allergist will begin by taking a detailed medical history, which will include questions about your lifestyle, eating habits, family and medical history, and medication use. Your doctor will also do a physical exam, and will check inside your nose for signs of inflammation.
Testing for allergic rhinitis may include:
Skin Test Skin testing is one of the easiest, most sensitive, and least expensive ways to diagnose rhinitis. A tiny allergen particle is placed under the skin with a needle. In 80% of cases, an allergic response is confirmed if the skin becomes raised or red within 20 minutes.
RAST Blood Test For this test, your doctor will take a blood sample to determine the level of antibody production in your body. This test is used to detect levels of immunoglobulin in response to a specific allergen. Such blood tests are less accurate than skin tests and should be done only when skin tests are not available.
Nasal Smear A sample of your nasal secretions may be taken and examined to identify the cause of the rhinitis or to rule out other allergic conditions.
