- The FeNO test is primarily used for diagnosing and monitoring asthma because elevated airway NO indicates inflammation. — 10 Tests to Assess Nitric Oxide Levels
- The FeNO test is not a general-purpose nitric oxide sufficiency screen; its clinical utility is specifically tied to airway inflammatory disease. — 10 Tests to Assess Nitric Oxide Levels
- Counterintuitively, higher exhaled NO signals a problem — NO that should be retained in the airways is being lost, indicating impaired recirculation and airway inflammation. — 10 Tests to Assess Nitric Oxide Levels
