What Does A1C Stand For?

A1C stands for ‘Glycated Hemoglobin’: a crucial factor used to monitor and manage blood glucose levels in those with diabetes or pre-diabetes. Learn more about A1C and its importance in diabetes care.


A1C, also referred to as HbA1c, is a term commonly used in reference to diabetes management. But what exactly does A1C stand for, and why is it so important in monitoring and controlling diabetes? This discussion delves into the critical role of A1C in diabetes care.

Understanding A1C

The term ‘A1C’ stands for ‘Glycated Hemoglobin.’ Hemoglobin is a protein found in red blood cells responsible for carrying oxygen throughout the body. When glucose (sugar) enters the bloodstream, it binds to the hemoglobin, creating ‘glycated hemoglobin.’

The Connection between A1C and Diabetes

For individuals with diabetes, more glucose is present in the bloodstream, resulting in a higher amount of glycated hemoglobin, or A1C. Therefore, an A1C test, which measures the percentage of glycated hemoglobin in the blood, becomes a vital tool to monitor blood glucose levels over a prolonged period.

  • Lower A1C Levels: A1C level below 5.7% is considered normal.
  • Pre-diabetes A1C Levels: An A1C level between 5.7% and 6.4% suggests pre-diabetes.
  • Diabetes A1C Levels: An A1C level of 6.5% or above on two separate tests indicates diabetes.

The Importance of Regular A1C Testing

Regular A1C tests allow individuals with diabetes or pre-diabetes to understand how well they are managing their blood sugar levels over time. This knowledge is fundamental because it helps to adjust treatment plans and prevent potential diabetes-related complications such as heart disease, nerve damage, kidney disease, and vision problems.


In summary, A1C stands for ‘Glycated Hemoglobin,’ a key indicator used to monitor and manage blood glucose levels in individuals with diabetes or pre-diabetes. Regular A1C testing can play a significant role in preventing the complications associated with uncontrolled diabetes.
