A multiple step process usually leads to the diagnosis of bronchiectasis. Many factors are considered and different tests are conducted. The evaluation for bronchiectasis often includes:

  • A complete medical history and physical examination by a healthcare provider.

  • A chest CT scan (a specialized X-ray which produces detailed slice-like pictures) of the lungs.

  • Breathing tests, called pulmonary function tests. These determine the presence and severity of abnormal airflow out of the lungs.

  • Specific screening or diagnostic tests for some of the possible underlying diseases that may cause bronchiectasis, based on the history and physical exam.
