Answer

Answer

Symptom improvement with asthma therapy is suggestive, but not diagnostic, of asthma. Symptoms alone do not necessarily reflect asthma severity. Infants may be treated empirically. In patients older than 5 years, however, objectively demonstrating reversible airflow obstruction with pulmonary function tests, if possible, is essential.
