Spirometry
Spirometry is a common and effective diagnostic test that can easily be done in your doctor's office or at a nearby hospital or clinic.
Bronchoscopy
A bronchoscopy is a test that allows the doctor to look through your nose or mouth into the trachea (windpipe) and down to the bronchi (large airways) in your lungs. This is done with a thin, flexible tube with a light and camera on the end called a bronchoscope.
