6 Tests Needed for Diagnosing Bronchiectasis

Bronchiectasis is a chronic lung disease which causes inflammation of the airways and leaves the patient unable to clear mucus from the lungs which increases the risk of infection.

Patients usually present symptoms such as a persistent cough and breathlessness, but in order to diagnose bronchiectasis a number of tests need to be carried out.

These tests include:

Blood Tests

Blood tests will help doctors to determine if there are any conditions present which are associated with bronchiectasis and to see if there are any underlying infections.

CT Scans

Sputum Sample

A sputum (or mucus) sample will be taken and tested to see if there any bacterial infections present or microbes which could be causing problems with the lungs.
