The 1999 WHO workshop ‘Allergic Rhinitis and its Impact on Asthma’ recommended:
- patients with persistent allergic rhinitis should be evaluated for asthma by history, chest examination, and possibly assessment of airflow obstruction before and after bronchodilator
- history and examination of the upper respiratory tract for allergic rhinitis should be performed in patients with asthma
