Asthma diagnosis is 7x more likely with a high FeNO level.3
Key highlights:
Using FeNO testing as your asthma risk estimator can help reduce exacerbations by up to 50%.4
Understanding the level of inflammation with FeNO can lead to improved asthma care.
Studies have shown that FeNO testing is a cost-effective way to improve patient outcomes.
Nobel Prize-Winning Science
FeNO stands for fractional exhaled nitric oxide (NO). NO is a molecule produced by the lungs that can be measured in exhaled breath. The use of NO in medicine was a real breakthrough, leading to a Nobel Prize in 1998.
Asthma: it's about inflammation
Although asthma is traditionally diagnosed with tools that measure airway obstruction, it's actually an inflammatory condition.1
As research progresses, opinion is changing. It is now understood that up to 84% of asthma patients have Type 2 airway inflammation.2
See inflammation clearly with FeNO
Understanding the level of inflammation with FeNO can lead to improved asthma care. FeNO levels are elevated in asthma and can provide healthcare professionals with the opportunity to see inside a patient’s lungs at the point-of-care.
More accurate diagnosis
With half of asthma cases misdiagnosed, lung function testing is not enough to make a decision.2 Asthma diagnosis is 7x more likely with a high FeNO level.3
This is Lucy
She gets breathless when she runs and occasionally at night. Lucy made an appointment to see her doctor to understand what was going on.
The doctor performed routine lung function testing and would have ruled out asthma. However when Lucy performed a FeNO test, the result was 73ppb, indicating airway inflammation.
This suggests that Lucy may have asthma.
Better managament
A high FeNO level indicates a greater risk of exacerbation. Using FeNO testing as your asthma risk estimator can help reduce exacerbations by up to 50%.4
This is Victor
He has had asthma since the age of 3 and is prescribed an inhaled corticosteroid. Victor still experiences exacerbations and recently visited his doctor.
The doctor wanted to check whether Victor was using his inhaler properly and offered him a FeNO test. Victor had a FeNO level of 163ppb, showing he is non-adherent to his medication and at risk of severe exacerbations. Seeing this number showed Victor how bad the situation actually was.
As part of his asthma management plan, Victor tested his FeNO regularly with the aim of reducing his FeNO to a normal level. Seeing his FeNO level reduce at every appointment motivated Victor to keep taking his medication. Victor’s FeNO is now 24ppb, his inflammation is under control and he has not had an asthma attack in the last year.
One size doesn't fit all
Exacerbation risks can be increased by modifiable factors such as high airway inflammation, reduced lung function, poor adherence to ICS or inadequate inhaler technique.1 Elevated FeNO values are associated with 3.2x greater risk of exacerbations when compared to low FeNO levels.4 Aiming to reduce high FeNO levels can help improve patient outcomes.5
