Sputum

However, there may be circumstances where a result is beneficial, such as in Cystic Fibrosis, Bronchiectasis, COPD, Chest Unit patients, those under chest physicians and immunocompromised patients.

Note: where Pseudomonas aeruginosa is isolated from Cystic Fibrosis and Bronchiectasis patients we apply sensitivity testing criteria (with the exception of isolates from GP patients).

Sensitivity testing will only be performed in the following cases.

• It is the first isolate.
  
• It is more than 12 months since the last isolate was tested.
  
• If the clinical details mention poor response to therapy, commencing therapy or there is a specific request for sensitivity testing.
