Bronchiectasis in children

Diagnosing bronchiectasis in children

Your doctor will ask you more about your child’s medical history and their symptoms.

If the doctor thinks that your child might have bronchiectasis then they will recommend a high-resolution computed tomography (HRCT) scan to see if their airways are widened. This is done using a type of X-ray machine.

They may also do other tests to try and find out how your child’s lungs were damaged. These might include:

  • tests on your child’s mucus to find out if bacteria are present
  • blood tests to check your child’s immune system
  • a brushing of the inside of your child’s nose to check if the hair-like structures on airway cells called cilia are working properly
  • a procedure to look into your child’s lungs using a small camera  on the end of a tube called a bronchoscope
  • tests on your child’s sweat to see if they have cystic fibrosis
