What Are A1C Levels?
A1C levels refer to the percentage of hemoglobin that is glycated, indicating the average blood glucose levels over a two to three-month period. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. When glucose enters the bloodstream, it binds to hemoglobin, forming glycated hemoglobin. The higher the glucose levels, the more hemoglobin becomes glycated, resulting in higher a1c levels.
The a1c test is an essential tool for diagnosing and monitoring diabetes. It provides a snapshot of long-term blood sugar control, which is crucial for preventing diabetes-related complications. The results of the a1c test are expressed as a percentage, with higher percentages indicating poorer blood sugar control.
For individuals without diabetes, a normal a1c level is below 5.7%. An a1c level between 5.7% and 6.4% indicates prediabetes, a condition where blood sugar levels are higher than normal but not high enough to be classified as diabetes. An a1c level of 6.5% or higher is used to diagnose diabetes.
Significance of A1C Levels in Diabetes Management
Maintaining optimal a1c levels is critical for individuals with diabetes, as it helps prevent both short-term and long-term complications. Consistently high blood sugar levels can lead to a range of health issues, including:
