Impact of the UK COVID-19 pandemic on HbA1c testing and its implications for diabetes diagnosis and management.

Ironically, failure to focus of the wider implications for people with DM and other groups with long-term conditions, may place them at increased risk of poor outcomes from SARS-CoV-2 infection itself, irrespective of the implications for their longer-term health prospects.
