Normal A1C Level Chart: What Your Results Mean
A1C, or glycosylated hemoglobin, is a blood test that measures your average blood sugar levels over the past 2-3 months. It's a crucial indicator of how well your diabetes treatment plan is working, and it can help you understand your risk of developing long-term complications. In this article, we'll explore what your A1C results mean and how to use a normal A1C level chart to understand your test results.
Understanding Your A1C Test Results

Your A1C test results are usually expressed as a percentage, ranging from 2% to 20%. The A1C level chart provided by your healthcare provider or found online can help you understand what your test results mean.
Normal A1C Levels
Normal A1C levels are typically defined as:
- <5.7%: Normal blood sugar levels, indicating low risk of diabetes-related complications
- 5.7-6.4%: Prediabetes, indicating an increased risk of developing type 2 diabetes
- 6.5% or higher: Diabetes, indicating high blood sugar levels and increased risk of complications
What Your A1C Results Mean
- Low A1C (<5.7%): This indicates that your blood sugar levels are within a normal range, and you're at low risk of developing diabetes-related complications.
- Prediabetes (5.7-6.4%): This indicates that your blood sugar levels are higher than normal, but not high enough to be classified as diabetes. You're at increased risk of developing type 2 diabetes and should work with your healthcare provider to develop a plan to lower your blood sugar levels.
- Diabetes (6.5% or higher): This indicates that your blood sugar levels are high, and you're at increased risk of developing diabetes-related complications, such as kidney damage, nerve damage, and vision problems.

A normal A1C level chart can help you understand your test results and track your progress over time. Here's how to use one:
- Find a normal A1C level chart online or provided by your healthcare provider.
