Why are HbA1c units changing?
The old, percentage way of reporting HbA1c values is known as the DCCT (Diabetes Control and Complications Trial) units.
The new mmols/mol values are known as the IFCC (International Federation of Clinical Chemistry) units.
Recommended A1c values
It is recommended that people with diabetes try to keep their HbA1c levels below 48 mmols/mol (under the new units).
