Asthma in Teens and Adults - Exams and Tests

(continued)

continued...

If you have persistent asthma and take medicine every day, your doctor may ask about your exposure to substances (allergens) that cause an allergic reaction. For more information about the following tests, see the topic Allergic Rhinitis.

Allergy tests include:

Skin tests. The skin on the back or arms is pricked with one or more small doses of allergens that might cause an allergy. The amount of swelling and redness at the sites of the skin pricks is measured to see which allergens cause a reaction. Skin tests are quick, simple, and relatively safe. Skin tests are needed if you are interested in allergy shots (immunotherapy).
Enzyme-linked immunosorbent assay (ELISA). A blood sample is taken from a vein and tested for immunoglobulin E (IgE) antibodies, which are produced in response to particular allergens.

Other tests may be done to see whether other conditions such as sinusitis, nasal polyps, or gastroesophageal reflux disease (GERD) are present.
