Abstract
The diagnosis of asthma is usually based on typical symptoms, family history, audible wheeze, peak flow, spirometry, possibly in conjunction with atopy and blood eosinophilia, as well as response to treatment. In cases for which the diagnosis is less clear-cut, other tests may be required, including impulse oscillometry (IOS), exhaled nitric oxide fraction (FeNO) and bronchial challenge testing (figure 1).
