Rhinitis is an inflammation of the nasal passages that can be caused by allergies, infections, or other irritants. In order to diagnose rhinitis, a doctor may perform a physical examination and review your medical history. They may also order tests such as a nasal swab, skin tests, X-rays, and blood tests.
Nasal Swab
A nasal swab is a test used to detect the presence of bacteria or viruses in the nose. During this test, a doctor or nurse will insert a swab into the nostril and gently rub it against the inside of the nose. The swab is then sent to a lab for analysis.
Skin Tests
Skin tests are used to determine if a person is allergic to a particular substance. During this test, a small amount of the allergen is placed on the skin and left for a few minutes. If a person is allergic, they will develop a rash or other skin reaction.
X-Rays
X-rays are used to look for signs of infection or inflammation in the nasal passages. X-rays can also be used to detect the presence of nasal polyps, which are growths that can block the nasal passages and cause breathing difficulty.
Blood Tests
Blood tests are used to detect the presence of antibodies that signal an allergic reaction. These tests can also be used to measure the level of inflammation in the body.
By performing these tests, a doctor can diagnose rhinitis and determine the best treatment plan. Treatment for rhinitis may include medications, lifestyle changes, and allergy shots.
