1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to an average glucose value in mg/dL. This provides a more intuitive understanding of glucose control for patients and healthcare providers.

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 an estimated average glucose level that corresponds to the measured HbA1c value, helping translate laboratory results into more familiar glucose units.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better understand their glucose control and facilitates more effective diabetes management and treatment adjustments.

4. Using the Calculator

Tips: Enter HbA1c value as a percentage. The value must be valid (greater than 0). The calculator will provide the corresponding estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: Many patients find glucose values in mg/dL more understandable than HbA1c percentages, making it easier to relate to their daily glucose monitoring.

Q2: How accurate is the eAG conversion?
A: The equation provides a good estimate based on population studies, but individual variations in glucose patterns may cause some discrepancy.

Q3: What is the relationship between HbA1c and average glucose?
A: HbA1c reflects average blood glucose levels over the previous 2-3 months, with higher percentages indicating higher average glucose levels.

Q4: Are there limitations to this conversion?
A: The relationship may vary in individuals with certain medical conditions that affect red blood cell turnover, such as anemia or hemoglobin variants.

Q5: What are typical target ranges?
A: Generally, an HbA1c below 7% (eAG below 154 mg/dL) is recommended for most adults with diabetes, but individual targets may vary.
