FENO, or fraction of exhaled nitric oxide measurements and induced sputum analyses are much more effective than conventional approaches at diagnosing asthma, say researchers.

FENO measurements are quick and easy to perform.

Sputum analysis is technically demanding and not routinely available.

FENO measurements may be readily incorporated into routine pulmonary function test procedures.

All this is according to a study you can read in the American Journal of Respiratory and Critical Care Medicine.
