U.S., Aug. 8 -- ClinicalTrials.gov registry received information related to the study (NCT07751705) titled 'Induced Sputum Collection in COPD Patients With and Without a Vibroacoustic Device' on Aug. 03.
Brief Summary: Induced sputum is a non-invasive method to collect samples from the airways. It involves inhaling a saline mist to loosen mucus, which is then coughed up. The samples are used to study markers of lung disease. In some people, this procedure yields only small amounts of sample.
