We aimed to determine the optimal cut-off values and series of investigations to diagnose asthma. We also explore the potential for novel tests of small airways function and biomarkers, which could be incorporated into future diagnostic pathways.Methods and analysis The Rapid Access Diagnostics for Asthma study is an observational study of 300 symptomatic patients with ‘clinician-suspected asthma’ and healthy controls (aged ≥3 to |
