For detailed observation and monitoring of processes in the lungs, our repertoire includes a variety of invasive and noninvasive methods that are being constantly improved.
Especially in clinical trials and proof-of-concept studies, it is often necessary to measure airway inflammation for monitoring diseases of the airways. This can be done by invasive bronchoscopic methods (e.g. bronchoalveolar lavage (BAL), bronchial biopsies) or by noninvasive methods such as sputum analysis and measuring nitric oxide (FeNO) concentrations in exhaled breath. We also test new methods and validate these in studies with patients suffering from respiratory diseases.
