The hemoglobin A1C test measures your average blood sugar over the past 2 to 3 months, giving an overall picture of blood sugar regulation. Here are the levels and what they mean: Normal: Less...
The A1C test measures the average amount of glucose that’s been attached to hemoglobin over time. Because the A1C test measures glucose levels over a period of time, it provides more information about blood sugar than a single blood sugar test.
This article provides an A1c chart to help you understand what different A1c levels mean and how healthcare providers use them to diagnose, monitor, and treat diabetes.
Understand the importance of HbA1c (Hemoglobin A1c) & its role in monitoring blood sugar levels. Know A1c charts, tests, levels, & normal ranges.
Doctors use the A1C test to check for prediabetes and diabetes. A range of 5.7–6.4% suggests a person may have prediabetes. Over 6.5% indicates diabetes. This test also helps doctors monitor...
Learn about the A1C test, a simple blood sugar test to diagnose prediabetes or diabetes, hemoglobin A1C and what do numbers mean, and how A1C relates to eAG.
You can match your A1c to an eAG using the conversion chart below. For example, an A1c of 5.9 is comparable to blood sugar of 123 mg/dl or 6.8 mmol/l. The exact formula to convert A1C to eAG (mg/dl) is: 28.7 x A1c – 46.7. The formula to converting mg/dl to mmol/l is: mg/dl / 18.
Specifically, the A1C test measures what percentage of hemoglobin proteins in your blood are coated with sugar (glycated). Hemoglobin proteins in red blood cells transport oxygen. The higher your A1C level is, the poorer your blood sugar control and the higher your risk of diabetes complications.
Learn what the A1C test is, how it works and is used to diagnose and monitor type 2 diabetes and prediabetes, when it doesn’t work, and how A1C relates to eAG.
What Are Normal Levels of Hemoglobin A1c (Chart)? In healthy people, the HbA1c level is less than 6% of total hemoglobin. A level of 6.5% signals that diabetes is present. Studies have demonstrated that the complications of diabetes can be delayed or prevented if the HbA1c level can be kept below 7%.
