1. What is HbA1c?

HbA1c (glycated hemoglobin) is a form of hemoglobin that is chemically linked to sugar. It provides a three-month average of blood glucose levels and is a crucial marker for diabetes management and diagnosis.

2. How Does the Calculator Work?

The calculator uses the HbA1c conversion formula:

Where:

• \( eAG \) — Estimated Average Glucose (mg/dL)
• 46.7 and 28.7 — Conversion constants

Explanation: This formula converts average blood glucose levels (eAG) measured in mg/dL to the corresponding HbA1c percentage value.

3. Importance of HbA1c Measurement

Details: HbA1c testing is essential for diabetes diagnosis, monitoring long-term glucose control, and assessing the risk of diabetes complications. It reflects average blood sugar levels over the past 2-3 months.

4. Using the Calculator

Tips: Enter your average blood glucose level in mg/dL. The value must be greater than 0. The calculator will provide the corresponding HbA1c percentage.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal HbA1c level?
A: For non-diabetics, normal HbA1c is below 5.7%. Prediabetes is 5.7-6.4%, and diabetes is 6.5% or higher.

Q2: How often should HbA1c be tested?
A: Diabetics should typically have HbA1c tested every 3-6 months, while those with prediabetes may be tested annually.

Q3: Can HbA1c be inaccurate?
A: Yes, conditions like anemia, hemoglobin variants, kidney disease, or recent blood loss can affect HbA1c accuracy.

Q4: What's the difference between HbA1c and daily glucose readings?
A: Daily glucose readings show immediate levels, while HbA1c provides a long-term average of glucose control.

Q5: How can I lower my HbA1c?
A: Through medication adherence, dietary changes, regular exercise, weight management, and consistent blood glucose monitoring.
