Don’t diagnose asthma without having performed lung function tests (including bronchodilating test and/or bronchial challenge).
Asthma-like symptoms (dyspnoea, chest tightness, cough, wheezing) are not enough to put a correct diagnosis of asthma.The international guidelines stress the need to perform lung function assessment in order to identify the presence of airway hyperreactivity or reversible bronchial obstruction. More in details, those with asthma-like symptoms and normal spirometry should undergo to a bronchial provocation challenge, while those with a basal bronchial obstruction should undergo to a bronchodilator test.
