  • Diagnosing a Chronic Cough

    There are several tests that doctors will use to diagnose your chronic cough. X-rays and CT scans will provide an image of the air passages. A lung function test will measure how well you breathe and identify if you have asthma. Mucus may be sent to a lab to see what bacteria or contaminants are in it. Another was a doctor can examine you is by inserting a scope to take a look inside your lung passages.
