An HbA1c value of 85 mmol/mol indicates the poorest long-term glycemic control among the values listed. Which of the following corresponds to 85 mmol/mol?

An HbA1c value of 85 mmol/mol indicates the poorest long-term glycemic control among the values listed. Which of the following corresponds to 85 mmol/mol?

• A. 58 mmol/mol
• B. 70 mmol/mol
• C. 85 mmol/mol
• D. 96 mmol/mol

Answer: (C)

HbA1c can be reported in different units, with mmol/mol (IFCC) being one common format. The task is to identify which option matches the given 85 mmol/mol value exactly. The only option that is numerically the same is 85 mmol/mol itself, so that is the correct match. In percentage terms, 85 mmol/mol roughly corresponds to about 9.9% HbA1c. The other values represent different levels (for example, 58 mmol/mol is about 7.5%, 70 mmol/mol about 8.6%, and 96 mmol/mol about 11%), confirming they are not equal to 85 mmol/mol.
