Diagnosis of Chronic obstructive pulmonary disease
People who live with COPD are often short of breath, have a persistent cough and a build up of phlegm.
The following tests can be carried out to eliminate other conditions, such as asthma:
- Spirometry (breathing test).This is the usual test to diagnose COPD. The doctor will ask you to breathe in and out of a tube that is connected to a machine, to see if your airways are narrowed. You may have your ‘peak expiratory flow’ measured or have to expel air from your lungs after using an inhaler. If there is no improvement after using the inhaler, it is more likely that you have COPD than asthma.
- Chest Radiography.This is an x-ray that will show any hyperinflation (excessive growth) of the lungs.
- CT scan.This is more sensitive than a chest radiograph and is particularly useful in diagnosing another lung disease called emphysema.
