Other Tests
In addition to these tests above, your doctor might need to do chest X-rays. The main goal is to find out the presence of any scar or inflammation around your lung areas, which can be possible symptoms of cystic fibrosis. Another option is the lung functioning test. During this procedure, your doctor will measure the ability of your lungs to pump carbon dioxide and oxygen. You would be asked to breathe into a device to perform the test. Lastly, a sputum culture test would determine whether you have any lung problems. [4]
