Pre-testing Requirements
To avoid a delay in processing, it is advisable to notify the laboratory when sending specimens and of any particular requirements.
Extra tests need to be clearly written on the request form e.g. TB, Fungi, Nocardia, Atypical pneumonia. Note on request form if patient is immunocompromised, Cystic Fibrosis, Bronchiectasis, Lung transplant.
Additional Specimen Information
When requesting multiple tests, it is essential to provide sufficient sample. Where only a small amount of sample is available, please indicate which tests are to be prioritised. To make sure specimens are well preserved please transport on ice. Place the ice in a separate outer bag to the specimen bag to contain any 'melt' that may affect patient labels and reduce possible contamination of the specimen.
