1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to average glucose levels 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 HbA1c measurement, helping translate laboratory results into more familiar glucose values.

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 in percentage. The value must be valid (HbA1c > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG provides glucose values in familiar units (mg/dL) that patients can relate to their daily glucose monitoring, making HbA1c results more meaningful.

Q2: What is the relationship between HbA1c and average glucose?
A: HbA1c reflects average blood glucose levels 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 HbA1c range is considered normal?
A: For non-diabetic individuals, HbA1c is typically below 5.7%. Values between 5.7-6.4% indicate prediabetes, and 6.5% or higher suggest diabetes.

Q5: How often should HbA1c be tested?
A: For diabetics, HbA1c is typically measured every 3-6 months to monitor long-term glucose control and treatment effectiveness.
