HbA1c reporting methods set to change

The way HbA1c levels are measured in people with diabetes will change on 1 October 2011. As a result, we have produced a simple-to-use online HbA1c converter.

Our easy-to-use online HbA1c converter tool is designed to help people with diabetes and healthcare professionals become familiar with the new measurements, and to ensure patients receive a smooth transition in their diabetes care during this period of change.

The Department of Health announced that HbA1c levels (long term blood glucose levels) would change from being measured in percentage units (%) to millimoles per mole (mmol/mol) in June 2009 after the International Federation of Clinical Chemistry (IFCC) recommended that the same measurements should be used worldwide. Diabetes UK welcomes the change in reporting but is concerned people may still be unfamiliar with the new measurements.

Natasha Marsland, Diabetes UK’s Clinical Advisor, said, "Adopting a global approach in the way HbA1c levels are measured will be of great benefit as it will now become easier for international laboratories and research trials to compare results across the world.

"However, we must ensure that this change does not impact on people with diabetes. It is vital that both clinicians and patients understand the new measurements to ensure the way they manage their condition and the care they receive is not compromised. There is still time to familiarise yourself with the new measurements before the change takes place and Diabetes UK has produced an online HbA1c converter tool to help people adjust to the new measurements."

HbA1c test measures blood glucose levels over previous few months

HbA1c tests measure how high or low a person’s blood glucose levels have been over the previous two-to-three months to monitor their long-term diabetes control. People with diabetes should receive an HbA1c test at least once a year.
