how to calculate a1c level

The A1C level is a measure of your average blood glucose levels over the past 2-3 months. It is expressed as a percentage and can be calculated using the following formula:

A1C (%) = (Average Blood Glucose (mg/dL) + 46.7) / 28.7

For example, if your average blood glucose level is 154 mg/dL, your A1C would be:

A1C = (154 + 46.7) / 28.7 = 7.0%

Here is a quick reference table for A1C levels and their corresponding average blood glucose levels:

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

6 126
7 154
8 183
9 212
10 240

It's important to note that the A1C test is typically performed in a lab or doctor's office, and the results are provided directly. This formula is useful for estimating your A1C based on your average blood glucose levels.
