What Is A1C?
A1C, or glycated hemoglobin, is a blood test that reflects average blood sugar levels over the past two to three months. It is often used to diagnose and monitor diabetes. The test measures the percentage of hemoglobin—the oxygen-carrying protein in red blood cells—that has glucose (sugar) attached to it.
When blood sugar levels are elevated, more glucose binds to hemoglobin, leading to a higher A1C level. The results are expressed as a percentage, with higher percentages indicating higher average blood sugar levels.
For people without diabetes, the normal range for A1C is typically below 5.7%. An A1C level between 5.7% and 6.4% may indicate prediabetes, while an A1C level of 6.5% or higher is often used to diagnose diabetes.
A1C testing is valuable for managing diabetes because it provides a longer-term view of blood sugar control compared to daily glucose monitoring. Healthcare professionals use A1C results to assess the effectiveness of diabetes treatment plans and make adjustments as needed. Regular monitoring of A1C levels is an important part of diabetes management.

Went to my doctor for a blood test and got my results. My A1C went from 898 to 790. I started my diabetic lowering diet today. No soda, no sugar, and no fat. Will be eating like a rabbit. No fat, sugar, no salt. AIC, also written as A1C or HbA1c, stands for hemoglobin A1c or glycated hemoglobin. It is a blood test that measures the average level of blood sugar (glucose) over the past 2-3 months.
In the context of diabetes, the A1C test is an important tool for monitoring and managing the disease. Here’s how it relates to diabetes:
- Indication of blood sugar control: The A1C test provides an estimate of how well a person’s blood sugar levels have been controlled over a period of around 3 months. It reflects the average amount of glucose that has been attached to the hemoglobin molecules in red blood cells during their lifespan.
- Diagnostic tool: For some individuals, an A1C level of 6.5% or higher can be used as a diagnostic criterion for diabetes, along with other tests and clinical observations.
- Treatment guidance: A1C results help guide treatment decisions for people with diabetes. Generally, lower A1C levels indicate better blood sugar control and a lower risk of complications.
- Treatment targets: Most diabetes organizations recommend an A1C target of less than 7% for adults with diabetes, but individualized targets may be set based on factors like age, life expectancy, and the presence of other medical conditions.
- Monitoring effectiveness: Regular A1C testing (usually every 3-6 months) is used to monitor the effectiveness of diabetes management strategies, such as diet, exercise, and medication regimens.
An elevated A1C level indicates higher average blood sugar levels and an increased risk of developing diabetes-related complications, such as nerve damage, kidney disease, and cardiovascular problems. By tracking A1C levels, healthcare providers can adjust treatment plans as needed to achieve better blood sugar control and reduce the risk of long-term complications.
