Why it's done

Your doctor may suggest a spirometry test if he or she suspects your signs or symptoms may be caused by a chronic lung condition such as:

  • Asthma
  • COPD
  • Chronic bronchitis
  • Emphysema
  • Pulmonary fibrosis

If you've already been diagnosed with a chronic lung disorder, spirometry may be used periodically to check how well your medications are working and whether your breathing problems are under control. Spirometry may be ordered before a planned surgery to check if your lung function is adequate for the rigors of an operation. Additionally, spirometry may be used to screen for occupational-related lung disorders.
