Can I calculate my A1C from my glucose readings?

While you cannot directly calculate your A1C from daily glucose readings, you can estimate it using your average blood glucose levels. The A1C test measures your average blood sugar over the past 2-3 months, while daily glucose readings provide snapshots of your blood sugar at specific times.

Here’s a general guide to estimate A1C based on average glucose levels:

Average Glucose (mg/dL) Estimated A1C (%)

126 6.0
154 7.0
183 8.0
212 9.0
240 10.0
269 11.0
298 12.0

For a more accurate A1C measurement, consult your healthcare provider and get a lab test.
