How is bronchitis diagnosed?
To work out if you have acute bronchitis, your doctor will ask you questions about your symptoms and perform a physical examination. This may include listening to your chest with a stethoscope to hear your breathing. They may also take a sample of mucus or a swab from your throat and send it off to a laboratory for testing, in order to work out the cause of the infection. The doctor may also do some breathing tests to assess for underlying asthma or narrowing of your airways.
