HbA1c (IFCC)
HbA1c (IFCC) is the same measurement as HbA1c but expressed in millimoles per mole (mmol/mol) using the International Federation of Clinical Chemistry standard, rather than the traditional DCCT percentage. The IFCC method is considered more standardized and is used in many European and international laboratories.
Why it matters: IFCC HbA1c and DCCT HbA1c measure the same thing — the two values are mathematically interconvertible. The IFCC standard was developed to improve measurement consistency across laboratories worldwide. Both formats are equally valid for diabetes management.

What might a high or low HbA1c (IFCC) mean?
IFCC HbA1c and DCCT HbA1c measure the same thing — the two values are mathematically interconvertible. The IFCC standard was developed to improve measurement consistency across laboratories worldwide. Both formats are equally valid for diabetes management.
What is the typical reference range for HbA1c (IFCC)?
The general-population reference range shown here is < 42 mmol/mol. Reference ranges describe the general population and are not a personal target — discuss your results with your physician.
