1. What is HbA1c?

HbA1c (Hemoglobin A1c) is a form of hemoglobin that is chemically linked to glucose. It provides a reliable measure of average blood glucose levels over the past 2-3 months and is a key indicator 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 crucial for diabetes diagnosis, monitoring long-term glucose control, and assessing the risk of diabetes complications. It provides a more comprehensive picture of blood glucose management than single glucose measurements.

4. Using the Calculator

Tips: Enter your average blood glucose level in mg/dL. The value must be a positive number. 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%. 5.7%-6.4% indicates prediabetes, and 6.5% or higher suggests diabetes.

Q2: How often should HbA1c be tested?
A: Diabetics should typically have HbA1c tested every 3-6 months. Those with well-controlled diabetes may test less frequently.

Q3: Can HbA1c be inaccurate in certain conditions?
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 monitoring?
A: Daily glucose monitoring shows immediate blood sugar levels, while HbA1c provides a 2-3 month average, offering a broader picture of glucose control.

Q5: Can I use this calculator for diabetes diagnosis?
A: This calculator provides an estimate only. Always consult a healthcare professional for proper diabetes diagnosis and management.
