Practical Example

Suppose your average blood glucose is 150 mg/dL. Using the calculator:

  1. Enter 150 in the input field.
  2. Click Calculate.
  3. The tool calculates your estimated HbA1c:

Estimated HbA1c=150+46.728.7≈6.85%\text{Estimated HbA1c} = \frac{150 + 46.7}{28.7} \approx 6.85\%Estimated HbA1c=28.7150+46.7​≈6.85%

  1. Your results show:
    • Average Glucose: 150 mg/dL
    • Estimated HbA1c: 6.85%

You can then copy these results or share them directly with your healthcare provider.
