HbA1c Conversion Chart

HbA1c Conversion Chart

I still can't get used to the new double digit numbers! Any other diabetic veterans need a conversion chart like me?

The measurement for HbA1c (Glycated Hemoglobin) has not changed from DCCT (Diabetes Control and Complications Trial) to mmol (millimoles). HbA1c is typically reported as a percentage and represents the average blood glucose levels over the past 2-3 months.

The values are usually given in percentage terms in the United States and some other countries, following the DCCT standard. In other regions, particularly in Europe, the HbA1c measurement is sometimes reported in millimoles per mol (mmol/mol), which is known as the International Federation of Clinical Chemistry (IFCC) units.

In the UK, the change from DCCT (Diabetes Control and Complications Trial) units to IFCC (International Federation of Clinical Chemistry) units for reporting HbA1c values occurred to standardise and align with international practices. The IFCC units, reported as mmol/mol, are used in many parts of the world, while the DCCT units, reported as a percentage, were more common in the United States.

The move to IFCC units provides a more consistent global standard for reporting HbA1c results, making it easier for healthcare professionals and researchers to communicate and compare data internationally. This change supports the efforts to streamline diabetes care practices and research methodologies on a global scale. It helps ensure that HbA1c values are universally understood, regardless of the country or healthcare system.
