1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to an estimated average glucose value in mg/dL. This helps patients and healthcare providers better understand average blood glucose levels over the previous 2-3 months.

2. How Does the Calculator Work?

The calculator uses the eAG equation:

Where:

• \( HbA1c \) — Glycated hemoglobin percentage
• 28.7 — Conversion coefficient
• 46.7 — Adjustment factor

Explanation: The equation provides a linear conversion from HbA1c percentage to estimated average glucose levels in mg/dL.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better relate to their diabetes management by translating the percentage into more familiar glucose units (mg/dL).

4. Using the Calculator

Tips: Enter HbA1c value as a percentage (e.g., 6.5). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: Many patients find it easier to understand their glucose control when expressed as average glucose levels rather than as a percentage.

Q2: What is the relationship between HbA1c and average glucose?
A: HbA1c represents the average blood glucose level over the past 2-3 months, with each 1% change in HbA1c corresponding to approximately 30 mg/dL change in average glucose.

Q3: Are there limitations to this conversion?
A: The relationship may vary between individuals, and the equation provides an estimate rather than an exact measurement for each person.

Q4: What are target eAG levels?
A: For most adults with diabetes, target eAG is below 154 mg/dL (HbA1c < 7%), though individual targets may vary based on specific circumstances.

Q5: How often should HbA1c be measured?
A: Typically every 3-6 months for people with diabetes, depending on treatment regimen and stability of glucose control.
