From the Research

The equivalent of HbA1c 10% is 86 mmol/mol, as indicated in the study 1. This conversion is crucial for understanding the level of glycemic control in patients with diabetes. HbA1c measures the percentage of hemoglobin with attached glucose, reflecting average blood glucose levels over the previous 2-3 months. A value of 10% indicates poor glycemic control, as it corresponds to an estimated average glucose of approximately 240 mg/dL (13.4 mmol/L).

For context, the target HbA1c for most adults with diabetes is below 7% (53 mmol/mol), though individual targets may vary based on age, comorbidities, and hypoglycemia risk. Such elevated levels (10% or 86 mmol/mol) significantly increase the risk of diabetes complications including retinopathy, nephropathy, neuropathy, and cardiovascular disease, and would typically prompt consideration of treatment intensification, as discussed in 1 and further elaborated in studies like 2, which models the incremental benefits on complication rates when targeting lower HbA1c levels in people with Type 2 diabetes and cardiovascular disease.

Key points to consider:

  • HbA1c is a critical marker for glycemic control.
  • The target HbA1c level can vary among individuals based on specific health conditions and risks.
  • Elevated HbA1c levels, such as 10% or 86 mmol/mol, are associated with a higher risk of diabetes-related complications.
  • Treatment intensification may be necessary for patients with high HbA1c levels to reduce the risk of complications, as suggested by studies like 3, which compares the effectiveness of different treatment regimens in achieving glycemic control.
