To acknowledge World Asthma Day on May 7th, we are raising awareness of this important health issue by discussing fractional exhaled nitric oxide (FeNO) testing, a safe and easy method to help diagnose and manage asthma. FeNO testing measures inflammation of the airways, allowing doctors to provide better treatment for patients experiencing asthma symptoms such as wheezing, coughing, or shortness of breath.

In the UK, over 8 million people, or approximately 12% of the population, have been diagnosed with asthma. However, some may have grown out of the condition, and 5.4 million people are receiving asthma treatment. Tragically, four people die every day because of asthma attacks, and a major study into asthma deaths (the National Review of Asthma Deaths) which looked at patient data from hospitals and GP practices, found that two-thirds of asthma deaths are preventable.

World Asthma Day serves as a reminder of the millions of people affected by this chronic respiratory condition, and the need for innovative solutions to improve patient care. FeNO testing aligns with this mission, offering a quick and non-invasive test to help patients receive a more accurate diagnosis and optimised treatment.

FeNO testing is suitable for patients as young as four years old, and the test is as simple as blowing bubbles through a straw into a drink. The testing process takes only 10 seconds for adults and six seconds for children, and the results are displayed on the testing device in less than two minutes. This revolutionary test could help patients reduce asthma symptoms and attacks, improving their treatment outcomes.

FeNO testing can be performed even by patients with reduced lung function, making it a versatile solution for individuals with varying levels of asthma severity. To ensure accurate results, patients should avoid eating, drinking, smoking, or engaging in strenuous exercise for at least one hour before the test.

This World Asthma Day, we encourage individuals to learn more about asthma management and the benefits of FeNO testing and more information can be found online at https://www.asthmaandlung.org.uk/
