Circassia / NIOX


NIOX® is a dedicated diagnostics and management company focused on asthma. Our market-leading NIOX® products are used by physicians around the world to help improve asthma diagnosis and management, and we support our customers with dedication to outstanding customer service and after sales support.


NIOX® is the first and only fractional exhaled nitric oxide (FeNO) testing device cleared by the FDA and commercially available at the point of care to provide objective measures of nitric oxide (NO), a biomarker of airway inflammation in asthma patients.  Just the way you use spirometry to monitor lung function, NIOX® can be used routinely to objectively measure and monitor airway inflammation.
