Lung function testing
Spirometry performed before and after treatment strategies, such as antibiotic use, may be of value in assessing improvements objectively.
Spirometry recommendations in The British Thoracic Society Guidelines for non-cystic fibrosis bronchiectasis:
adults and school age children – initial assessment
adults attending specialist care – annual spirometry performed
patients with immune deficiency or primary ciliary dyskinesia – spirometry at least four times a year
