Breath and blood tests could revolutionize asthma diagnosis in kids
NCT ID NCT07011394
First seen May 14, 2026 · Last updated Jun 20, 2026 · Updated 10 times
Summary
This study looks at whether two simple tests—a breath test (FeNO) and a blood test—can help diagnose asthma in children aged 6 to 17. Currently, diagnosing asthma often requires complex hospital tests. The goal is to see if these easier tests work well enough to be used in regular doctor's offices, especially for children whose initial breathing tests are unclear.
