There will also be biobanking of sputum samples and/or bronchoscopy samples (such as BALs & lung washings) that are being obtained for clinical purposes. Also, for those consented for biobanking blood and urine will be collected, separate from clinical care, and stored in the biobank. The Canadian Biosample Repository (CBSR) will be storing our biobanked samples. The investigators will be following the CBSR policies for storage and security. Tissue research will be conducted in the future, and separate ethics approval will be obtained for each project.
