Asthma Diagnosis
The symptoms of asthma can mimic several other conditions, and a doctor must take a thorough history to rule out other diseases. Questions will likely be asked about how and when symptoms occur, and if there is a family history of allergies and asthma or occupational exposure to chemicals. If asthma is suspected, tests (called pulmonary function tests) will probably be done to measure, among other things, the volume of your lungs and how much air you exhale. Other tests may include chest and sinus x-rays, blood tests, or allergy tests.
