NICE asthma guideline: diagnosis and monitoring
In the UK, approximately 5.4 million people (1.1 million of whom are children) currently receive treatment for asthma. The causes of asthma are not well understood but genetics and environmental factors are known to play a part. Diagnosis of asthma is typically based on a detailed history as there is no gold standard test to confirm a diagnosis. Some studies have suggested that up to 30% of asthma diagnoses in adults could be inaccurate, while other studies claim that asthma could currently be under diagnosed.
This Guidelines summary covers the initial assessment, diagnosis, and monitoring of asthma in adults, young people, and children.
