The Association for Respiratory Technology & Physiology have recently released a position statement on race-neutral spirometry reference values, endorsing the use of GLI Global reference values for spirometry. The position statement has also been supported by ARNS.
The key messages of the statement are:
• Self-identified race/ethnicity will no longer be required for lung function interpretation.
• GLI Global reference equations are currently for spirometry only.
• Interpretation methods remain the same.
• Retrospective reference data will need to be recalculated.
• Availability on equipment will vary.
• Where GLI Global is unavailable, GLI Other can be utilised.
