1. What is the A1c Calculator?

The A1c Calculator estimates Average Glucose (eAG) from Hemoglobin A1c percentage. It provides a more intuitive understanding of glucose control by converting A1c to the same units (mg/dL) as daily glucose monitoring.

2. How Does the Calculator Work?

The calculator uses the eAG formula:

Where:

• \( A1C \) — Hemoglobin A1c percentage (%)
• \( eAG \) — Estimated Average Glucose (mg/dL)

Explanation: The equation converts A1c percentage to estimated average glucose in mg/dL, helping patients relate A1c results to their daily glucose meter readings.

3. Importance of eAG Calculation

Details: eAG provides a more tangible understanding of average blood glucose levels over the past 2-3 months, helping patients and healthcare providers better assess diabetes management and treatment effectiveness.

4. Using the Calculator

Tips: Enter A1c value in percentage. The value must be valid (A1c > 0). The calculator will provide the estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between A1c and eAG?
A: eAG translates A1c percentage into average glucose levels in mg/dL, making it easier for patients to understand their A1c results in the context of their daily glucose monitoring.

Q2: What are normal A1c values?
A: Normal A1c is below 5.7%. 5.7%-6.4% indicates prediabetes, and 6.5% or higher indicates diabetes.

Q3: How often should A1c be tested?
A: For people with diabetes, A1c should be tested at least twice a year. If treatment changes or glucose levels are not meeting targets, testing every 3 months is recommended.

Q4: Are there limitations to this conversion?
A: The formula provides an average estimate. Individual variations in glucose fluctuations and hemoglobin characteristics may affect the accuracy of the conversion.

Q5: Can eAG replace daily glucose monitoring?
A: No, eAG provides an average but doesn't show glucose variability or hypoglycemic episodes. Daily monitoring remains essential for diabetes management.
