Average Blood Sugar Calculated From The Hba1c 108

eAG Calculation Formula:

\[ eAG (mg/dL) = 28.7 \times ((HbA1c (mmol/mol) / 10.929) + 2.15) - 46.7 \]

1. What is eAG Calculation?

Estimated Average Glucose (eAG) calculation converts HbA1c values from mmol/mol to mg/dL, providing an average blood glucose level over the past 2-3 months. This helps patients better understand their diabetes control in familiar glucose units.

2. How Does the Calculator Work?

The calculator uses the eAG conversion formula:

\[ eAG (mg/dL) = 28.7 \times ((HbA1c (mmol/mol) / 10.929) + 2.15) - 46.7 \]

Where:

\( HbA1c \) — Glycated hemoglobin in mmol/mol
\( eAG \) — Estimated average glucose in mg/dL

Explanation: This formula provides a mathematical conversion between HbA1c measured in IFCC units (mmol/mol) and estimated average glucose levels in mg/dL.

3. Importance of eAG Calculation

Details: eAG helps translate HbA1c results into average glucose values that patients can relate to their daily blood glucose monitoring, improving understanding of diabetes control and treatment adherence.

4. Using the Calculator

Tips: Enter HbA1c value in mmol/mol. The value must be greater than 0. The calculator will provide the corresponding estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between HbA1c and eAG?
A: HbA1c is a percentage or mmol/mol value representing glycated hemoglobin, while eAG is the estimated average glucose level in mg/dL that corresponds to that HbA1c value.

Q2: Why convert HbA1c to eAG?
A: Many patients find it easier to understand their diabetes control when expressed as average glucose levels (mg/dL) rather than HbA1c percentages or mmol/mol values.

Q3: How accurate is the eAG calculation?
A: The formula provides a reliable estimate based on large clinical studies, though individual variations may occur due to factors affecting red blood cell turnover.

Q4: Can eAG replace daily glucose monitoring?
A: No, eAG provides an average but doesn't show glucose fluctuations. Daily monitoring is still essential for managing insulin doses and detecting hypoglycemia/hyperglycemia.

Q5: What are target eAG levels for diabetes management?
A: Generally, eAG below 154 mg/dL corresponds to HbA1c <7% (53 mmol/mol), but individual targets should be set with healthcare providers based on specific circumstances.
