Asthma should not be diagnosed without performing spirometry.

Spirometry is the best tool for assessing lung function in asthmatic children, and allows to define the disease severity, monitor the response to pharmacological treatment and achieve symptoms control. Patient’s history and physical examination alone, not combined with spirometry results, may underestimate or overestimate asthma control. In addition to the economic burden to the Health Care System, the consequences of misdiagnosis include a delay in the diagnosis and in the start of treatment. Spirometry is recommended:• at the first assessment, in order to determine the disease severity;
• after treatment is started, during the follow-up visits in order to optimize therapy;
• when exacerbations occur;
• at least every 1-2 years in cases with intermittent asthma. The response to bronchodilator should be carried out regularly.
Spirometry can be achieved in children as young as five years if criteria for acceptability are satisfied.
