First seen Nov 19, 2025 · Last updated May 14, 2026 · Updated 19 times

Summary

This study looked at whether two simple tests—a breath test (FeNO) and a blood test—can help diagnose asthma more easily than current hospital-based breathing tests. Researchers studied 123 people with suspected asthma to see if these tests could accurately identify the disease and measure airway inflammation. The goal is to make asthma diagnosis faster and more accessible, especially for children.
