What is Nontuberculous Mycobacteria (NTM) Lung Disease?
www.thoracic.orgSputum (mucus) is looked at under the microscope to see if NTM bacteria are present. Cultures to try to grow the bacteria are also done. Some NTM grow rapidly in culture—within a few days—but some NTM types take several weeks to be detected in the culture. Collection of three early-morning sputum samples on different days is preferred for
