Breath and blood tests could revolutionize asthma diagnosis in kids
NCT ID NCT07011394
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether two simple, non-invasive tests—a breath test (FeNO) and a blood test (eosinophil count)—can accurately diagnose asthma in children aged 6 to 17. Currently, diagnosing asthma often requires complex hospital-based breathing tests. The researchers aim to see if these easier tests work well in primary care settings, especially when standard spirometry is unclear. About 123 children with asthma-like symptoms will participate.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- FeNO breath test and blood eosinophil count
- What this could lead to
- If successful, these simple tests could help doctors diagnose asthma in children more quickly and easily, without needing hospital-based breathing tests.
- What could go wrong
- This is a small, early-stage study focused on diagnosis, not treatment. The tests may not be accurate enough to replace current methods, and results may not apply to all children.
