Here are some FAQs regarding the National Register for Spirometry.

Which diagnostic tests are expected?

It will be important for commissioners to ensure that their local services include the following:

Detailed relevant family and personal medical history recorded in notes:

Ensure clinicians have a good understanding of best practice and consider regular audits of practice using British Asthma/ SIGN guideline London asthma standard for children and young people and NICE Quality Standards – Asthma quality standard [QS25] and have received training in asthma diagnosis and management.

Objective measurement of lung function is important in the diagnosis and assessment of acute and chronic asthma. This guide on peak flow measurement will provide support to clinicians.
