FeNO breath test to help diagnose asthma
Part of Immune system & allergy, Lungs & breathing clinical trials.
This trial is testing whether a simple breath test called FeNO can help doctors diagnose asthma more accurately. It's for people who have symptoms that might be asthma, but haven't been diagnosed yet.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You are visiting a lung doctor because asthma is suspected.
- You have not been previously diagnosed with asthma.
- If you had a respiratory infection (like a cold or bronchitis) in the last 3 weeks, you'll need to wait until it's been more than 3 weeks since you were sick.

This study tests a new way of measuring lung function (called impulse oscillometry) during routine asthma check-ups. It looks at whether this helps doctors decide when to change asthma medicines.
This study looks at a specific kind of inflammation (called Type 2) in people with asthma. Researchers want to see how common it is and how it affects asthma symptoms.
This trial uses a simple inflammation test (inflammometry) to help diagnose asthma more accurately in people aged 6 and older who have been sent by their primary care doctor for standard breathing tests. It aims to improve the diagnosis process and reduce delays.
This trial tests a handheld device that measures nitric oxide in your breath to see if it can help monitor asthma. You may qualify if you have uncontrolled asthma and can use the device at home.
This study is testing a new way to diagnose asthma in children and teens using simple breathing tests. If your regular breathing test wasn't clear, this might give a more accurate answer.
This study compares simple breathing tests (oscillometry and FeNO) used by your primary care doctor against a specialist's diagnosis to see if they can accurately tell if you have asthma or COPD. If you have symptoms like wheezing, cough, or shortness of breath but haven't been diagnosed yet, this trial may help improve how these conditions are found.
