If you have symptoms of bronchiectasis a GP will listen to your chest.

They may arrange some tests such as:

• testing a sample of your phlegm (mucus) to check for an infection
• a chest X-ray
• a test where you breathe into a machine to check how well your lungs are working (spirometry test)
• blood tests

If these tests show you could have bronchiectasis, you'll be referred to a specialist for more tests such as a CT scan to confirm the diagnosis.

You may also need other tests to find the cause.
