What tests can help diagnose asthma?

ANSWER

Some asthma tests, such as pulmonary function tests, measure lung function. Other tests check if you are allergic to specific foods, pollen, or other particles. Blood tests give a picture of your overall health. There are tests that measure levels of immunoglobulin E (IgE), a key antibody that’s released during an allergic reaction.
