Better sputum collection could speed up NTM lung infection diagnosis

This study looked at three ways to collect mucus samples from the lungs of people with a hard-to-diagnose infection called pulmonary nontuberculous mycobacterial (NTM) disease. Researchers compared throat swabs, coughed-up phlegm, and phlegm brought up using a mist inhaler to see which method works best for detecting the bacteria. The goal was to find a more accurate and easier way to diagnose this lung infection early. No treatment was given—only sample collection.
