Accurately assess airway inflammation at the
point-of-care, with NIOX VERO®

What Is FeNO Testing?

FeNO stands for fractional exhaled nitric oxide and reflects the amount of nitric oxide produced by the lungs. FeNO testing is used to assess levels of inflammation in the airways, right at the point-of-care. Most national and international guidelines recommend feNO testing to improve asthma outcomes. ^1-6

The Most Convenient Biomarker

Simple: Result is a single value, to quickly understand the level of airway inflammation
Immediate: Test performed and results obtained in less than 2 minutes at the point-of-care
Non-invasive: Only requires a gentle breath, similar to blowing bubbles in a drink
Easy: Can be performed in young children and by patients with severely reduced lung function
Safe: Gentle exhalation very unlikely to trigger a cough. Not an aerosol-generating procedure

The Science Behind FeNO

Type 2 airway inflammation is present in up to 84% of asthma patients.⁷ In those patients, interleukins IL-4 and IL-13 upregulate the activity of the iNOS (inducible Nitric Oxide Synthase) enzyme, which produces NO in the airways.⁸ Levels of exhaled NO are increased and can be accurately measured with FeNO testing. Inhaled corticosteroids suppress a wide rage of inflammatory pathways and reduce FeNO levels.⁹

Instantly transform your asthma care

FeNO testing can give you more confidence in diagnosing and managing asthma. An asthma diagnosis is 7x more likely with a high FeNO level.¹⁰ Paitents with a high FeNO also have up to 3.2x greater risk of exacerbation.¹¹ Using FeNO testing to guide asthma management can help reduce exacerbations by up to 50% through optimizing therapy and uncovering non-adherence.¹² In addition, FeNO testing can be used as an educational tool as patients visualize what is happening in their lungs, encouraging them to take their treatment as prescribed.
