FeNO Testing

Accurately assess and monitor airway inflammation.2,5

Whilst airway inflammation is known to be the major underlying characteristic of asthma, there are few methods which directly measure this. Evaluating airway inflammation using sputum eosinophils or airway biopsy can be expensive, invasive, time-consuming, and is often not readily available. FeNO testing provides a fast and accurate method to support diagnosis and management of asthma at the point of care.

The majority of patients with asthma have Type 2/eosinophilic driven airway inflammation.6 The associated higher levels of nitric oxide (NO) in their exhaled breath can be simply measured to support optimal management of the condition7
