Better asthma diagnosis for children and teens
Part of Immune system & allergy, Lungs & breathing clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 6 and 17 years old.
- You have symptoms that might be asthma (like wheezing or coughing).
- You have been sent for a special breathing test (methacholine challenge) by a doctor who is not a lung, ear-nose-throat, or allergy specialist.
- Your basic breathing test (spirometry) was not clear enough to diagnose asthma.
- You have not used a steroid inhaler or steroid pills in the last 48 hours.
- You have not smoked in the last 6 hours, had a cold or lung infection in the last 4 weeks, or have major lung or heart disease.

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 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.
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.
This trial studies new technologies to help doctors diagnose asthma and better understand airway inflammation. It may help you (or healthy volunteers, if eligible) by allowing your breathing tests and inflammation markers to be measured with newer diagnostic tools.
This study looks for biological “markers” that may help explain why asthma starts and how it changes over time in children. It may help your child’s doctors understand asthma better, especially for diagnosis or tracking.
This trial studies how well a special breathing test (forced oscillations) works during a methacholine challenge in children. It may help doctors better measure breathing sensitivity and guide treatment decisions.
