1. What is the A1c Blood Test?

The A1c blood test (hemoglobin A1c) measures your average blood glucose levels over the past 2-3 months. It provides a comprehensive view of blood sugar control and is commonly used to diagnose and monitor diabetes.

2. How Does the Calculator Work?

The calculator uses the eAG formula:

Where:

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

Explanation: This formula converts A1c percentage to estimated average glucose in mg/dL, making it easier to understand daily glucose levels.

3. Importance of eAG Calculation

Details: Converting A1c to eAG helps patients better understand their glucose control in familiar units (mg/dL) and facilitates communication between patients and healthcare providers about diabetes management goals.

4. Using the Calculator

Tips: Enter your A1c percentage value. The value must be a positive number representing your hemoglobin A1c test result.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal A1c level?
A: For people without diabetes, a normal A1c level is below 5.7%. Levels between 5.7%-6.4% indicate prediabetes, and 6.5% or higher indicate diabetes.

Q2: How often should A1c be tested?
A: People with diabetes should typically have their A1c tested every 3-6 months, depending on their treatment plan and how well their blood sugar is controlled.

Q3: Can A1c results be inaccurate?
A: Yes, certain conditions like anemia, kidney disease, or recent blood loss can affect A1c accuracy. Always discuss results with your healthcare provider.

Q4: What's the difference between A1c and daily glucose readings?
A: A1c provides an average over 2-3 months, while daily glucose readings show your blood sugar at specific moments. Both are important for diabetes management.

Q5: How does eAG relate to my glucose meter readings?
A: eAG represents your average glucose level, which should be similar to the average of your daily glucose meter readings over the same period.
