New treatment option for Diagnosis
Official title Fractional Exhaled Nitric Oxide (FeNO)- Test as add-on Test in the Diagnostic Work-up of Asthma
ClinicalTrials.gov ID: NCT06230458
What this study is testing
- What it's testing
- The Global Initiative of Asthma Guideline (GINA) recommends a flowchart to diagnose asthma with first-step spirometry with reversibility and a bronchial challenge test (BPT) with histamine or methacholine as a second step. This multi-center prospective care evaluation study compares the 'standard asthma diagnostic work-up' (spirometry with reversibility and BPT) to the 'new asthma diagnostics work-up' (FeNO-test as an intermediate step between the spirometry with reversibility and the BPT), intending to determine the impact of the FeNO-based strategy, in terms of the number of avoided BPTs, cost-effectiveness and reduced burden to the patient and health care.
