HbA1c to Average Glucose Converter

HbA1c to Average Glucose Converter MCP Connector for Claude

A+

Estimate average glucose, time in range, and glucose variability from HbA1c.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides deterministic tools to convert HbA1c percentages into clinical glucose metrics. Using the ADAG formula, it calculates estimated average glucose (eAG) in both mg/dL and mmol/L. It also provides statistical estimates for Time in Range (TIR) and the Coefficient of Variation (CV) based on standard regression models. Use calculate_glucose_metrics to get a full profile of glucose metrics, get_conversion_constants to see the underlying math, or validate_a1c_range to check if a value is clinically valid.

Based on this HbA1c percentage, what are my estimated average glucose, time in range, and glucose variability? My HbA1c is 7.0%.

For an HbA1c of 7.0%, your estimated average glucose is 154 mg/dL (8.5 mmol/L), with an estimated Time in Range of approximately 70% and a Coefficient of Variation of 33%.

What are the mathematical constants used for these glucose conversions?

The conversion uses a mg/dL to mmol/L factor of 18.018 and assumes a standard CV range for statistical estimations.

Is an HbA1c of 4.5% valid for estimation?

Yes, an HbA1c of 4.5% is within the clinically valid range for these estimation models.

The estimated average glucose (eAG) is calculated using the ADAG formula: (28.7 × HbA1c) - 46.7.
