Isolation of nontuberculous mycobacteria (NTM) from the sputum of individuals with CF is an increasingly common finding, and the lack of an evidenced-based approach to the diagnosis of NTM disease has been identified as one of the greatest unmet needs within the CF community. Current evidence predicts that the prevalence of NTM will remain relatively high in the CF population. Approaches to NTM disease diagnosis differ widely between centers. This study is observational and follows current best practices. The study will help standardize the diagnosis and collect relevant data associated with the diagnosis of NTM disease to build a framework for future therapeutic trials.
