What is A1C and How Does it Relate to Blood Sugar?

A1C, also known as glycated hemoglobin, is a blood test that provides an average measure of your blood sugar levels over the past 2-3 months. When glucose (sugar) in your blood attaches to hemoglobin (the protein in red blood cells that carries oxygen), it forms glycated hemoglobin. The higher your average blood sugar levels, the more glucose binds to hemoglobin, resulting in a higher A1C level.

How A1C Works:

Glucose Binding: When blood sugar levels are high, glucose molecules attach to hemoglobin in red blood cells.
Formation of Glycated Hemoglobin: This process creates glycated hemoglobin, which remains in the red blood cells for their lifespan (about 3 months).
A1C Measurement: The A1C test measures the percentage of hemoglobin that has glucose attached.
Average Blood Sugar Reflection: The result provides an estimate of your average blood sugar levels over the preceding 2-3 months.

The Relationship Between A1C and Blood Sugar:

Direct Correlation: A1C is directly proportional to your average blood sugar levels. Higher average blood sugar translates to a higher A1C level, and vice versa.
Different Metrics, Complementary Information: While daily blood sugar readings provide a snapshot in time, A1C offers a more comprehensive view, smoothing out fluctuations to reveal overall control.
A1C as a Long-Term Indicator: Unlike a single blood sugar reading, A1C reflects the impact of dietary habits, physical activity, and medication adherence over an extended period.

Example Correlation:

| A1C (%) | Estimated Average Glucose (mg/dL) | | :----------: | :-----------------------------------: | | 6 | 126 | | 7 | 154 | | 8 | 183 | | 9 | 212 | | 10 | 240 |

This table illustrates the direct relationship between A1C percentages and estimated average glucose levels, helping patients understand their glycemic control in a broader context.
