The issue affects both type 1 and type 2 diabetes, as the HbA1c test is used in monitoring both conditions. However, HbA1c is not used in the same way to diagnose type 1 diabetes, so the impact on T1D diagnoses is expected to be far less. People with type 1 diabetes also have continuous glucose monitoring (CGM) data to support and guide their care, further reducing any potential impact.
In contrast, HbA1c is a central tool for type 2 diabetes diagnosis and management, which is why recent reports have focused on that group.
The National Diabetes Audit shows no increase in type 1 diagnoses during the period when the calibration issue occurred (April – December 2024), and none of the 16 hospital laboratories involved have reported any impact on type 1 testing.
If you live with type 1 diabetes, this means your diagnosis and ongoing care should not have been affected by the issues raised in recent reports. As always, if you have individual concerns about your test results or diabetes care, we encourage you to speak directly with your healthcare team.
We remain in close contact with NHS England and regulators to ensure people with type 1 diabetes continue to receive safe, accurate testing and care.
