eAG Formula:
| From: | To: |
The eAG (estimated Average Glucose) formula converts HbA1c values in mmol/mol to an estimated average glucose level in mg/dL. This provides a more intuitive understanding of average blood sugar levels over the past 2-3 months.
The calculator uses the eAG formula:
Where:
Explanation: The formula mathematically converts the HbA1c percentage equivalent to an average glucose value that patients can more easily relate to their daily glucose measurements.
Details: Converting HbA1c to eAG helps patients better understand their diabetes control by translating the long-term marker (HbA1c) into the same units (mg/dL) used for daily glucose monitoring.
Tips: Enter the HbA1c value in mmol/mol. The value must be a positive number. The calculator will provide the estimated average glucose in mg/dL.
Q1: Why convert HbA1c to eAG?
A: eAG helps patients relate their HbA1c results to their daily glucose meter readings, making it easier to understand their diabetes management.
Q2: What is a normal eAG range?
A: For non-diabetic individuals, eAG is typically between 70-126 mg/dL. Diabetes management targets vary but often aim for eAG below 154 mg/dL (HbA1c < 7%).
Q3: How often should HbA1c be measured?
A: Most people with diabetes should have HbA1c tested every 3-6 months, depending on their treatment plan and stability of glucose control.
Q4: Are there limitations to eAG calculation?
A: The formula provides an average and doesn't reflect glucose variability. Individual results may vary based on factors like hemoglobin variants or conditions affecting red blood cell turnover.
Q5: Can eAG replace daily glucose monitoring?
A: No, eAG complements but doesn't replace daily glucose monitoring, which provides immediate feedback on glucose levels and helps adjust therapy in real-time.
