What are the tests for adult asthma?

Tests... To diagnose asthma, one needs to diagnose recurrent bronchospasm and airway inflammation. This can be done by a doctor based on clinical grounds (example: the doctor hears wheezing/coughing on more than one occasion and it resolves completely with treatment). Or, the diagnosis can be made in the pulmonary function lab if this diagnosis is suspected but the physical exam is normal.

Lung function. The two main tests are spirometry, in which you blow hard into a computer sensor that measures how well your lungs work, and the fractional excretion of nitric oxide, which is a measure of the amount of inflammation in the lungs. Particularly in people younger than 50, allergy tests can help to diagnose the triggers for your asthma.
