I think I might have COPD. What tests might my doctor do to determine if that's the case?
COPD is diagnosed with lung function testing (pulmonary function tests), such as spirometry. Spirometry measures lung function and capacity. It involves exhaling into a tube connected to a machine.
COPD can also be assessed with a chest X-ray, CT scan, arterial blood gas assessment, and other laboratory tests.
There's also the 6-minute walk test. It's a test that measures the functional status of those with COPD. It provides information about the possibility of a drop in oxygen saturation. This helps determine if you need supplemental oxygen.
