A1C Chart

Before going into the details of A1C conversion chart; first, let us see some basics about a1c.

What is an A1C? The A1C also known as HbA1c or glycated hemoglobin is a blood test that shows how well your diabetes management plan is working. 

What do the A1C numbers mean? The A1c test tells you your average level of blood sugar over the past 2 to 3 months. 

How Is Hemoglobin A1c Measured? A1c measurement is by separating hba1c based on the charge and size from the other hemoglobin A components in blood by a procedure called high pressure (or performance) liquid chromatography (HPLC).

What is a good a1c level? Normal A1c value for those not diagnosed with diabetes (healthy non-diabetic) is in the range of 4.2 to 4.6%. For more visit Healthy A1C Goal.

How often should I take A1C test? Your doctor mostly insists to take A1C test 2 to 4 times a year.

How accurate is the A1C test? The A1C is now standardized, and the acceptable variance can be within 0.5%. So if your result is 6.5%, then the actual reading could be anywhere from 6 to 7% (i.e. 6.5 - 0.5 to 6.5 + 0.5). There are some health conditions that could affect the accuracy of the A1c.

What is eAG? eAG is estimated average glucose is a newer term you may see reported by your doctor. However, eAG is not the same as the average of your meter reading. The a1c chart in this article provides eAG (blood glucose in mg/dl or mmol/L).

What is the difference between eAG and the average on the glucose monitor? Mostly meter average is lower than eAG because people with diabetes check their blood glucose more often when they are low, so the meter readings average likely to be lower than eAG.

Glucose monitor measures your blood glucose at the moment, whereas eAG or A1C represent an average of your glucose levels 24 hours a day, including times when diabetics are less likely to check their blood glucose.

Can the A1C test be used for the diagnosis of prediabetes and diabetes? Yes, nowadays doctors use A1C test for diabetes screening because it does not require fasting. However, to diagnose diabetes it is advisable to use other diabetes diagnosis tests along with a1c.

What are the benefits of the A1C test? Studies confirm the importance of the A1C test to avoid diabetes complications. Popular studies DCCT, UKPDS, EDIC & EPIC-Norfolk, confirms the link between A1C and diabetes complications. For more visit Benefits of A1C in Diabetes Control

What are the limitations of the hemoglobin A1c test? HbA1c may be increased or decrease falsely in certain medical conditions. For more visit A1C Test Errors

How can I get my a1c down quickly? Achieving your set target is not an easy job. It requires patience, interest to learn, ability to analyze, willpower to accept failures and stick with lifestyle changes. For more visit How to lower A1C?

Does aging affect A1C level? A1C levels have a positively associated with age in the nondiabetic individual. A1C was 6.0% and 5.6% for nondiabetic individuals aged less than 40 years in FOS & NHANES respectively, and also 6.6% and 6.2% for individuals aged 70 years. 

Why do you need an A1C level chart?

The A1C result is significant for long-term glucose monitoring. It helps to know, how well or bad your past 3 months blood glucose control.

A1C test in % is confusing, because we used to measure glucose levels in mg/dl or mmol/l. A1C chart help convert A1C in % to its equivalent average blood glucose, which is easier to interpret.

DCCT A1C conversion formula seems to work best in people with high blood sugars. Because this formula derived from such group.

A1C level chart in this article shows the relation between A1C and its average blood sugar equivalent, based on the DCCT A1C conversion formula.

Diabetes Control and Complications Trial or DCCT, New England Journal of Medicine 1993; 329:977-986. They studied 1400 T1D; quarterly A1C tests were the primary measure of glycemic control. The study subjects performed quarterly 24-hour, 7-point capillary blood glucose profiles in the home. These are 3 pre-meal tests, 3 post-meal (after 90 minutes) tests, and 1 at bedtime.

Diabetes Care 25:275-278, 2002 result showed a linear relationship between HbA1c and eAG. eAG in mg/dl = (35.6 x HbA1c) - 77.3 or eAG in mmol/l = (1.98 x HbA1c) – 4.29.

Reference: "Defining the Relationship between Plasma Glucose and HbA1c, Analysis of glucose profiles and HbA1c in the Diabetes Control and Complications Trial," Diabetes Care 25:275-278, 2002.

Dr. Richard K. Bernstein, the author of the popular book "Diabetes Solution." He is the first who succeeded using low-carb diet for his type-1 diabetes control (with an A1C of 4.2 to 4.6).

Dr. Richard K. Bernstein recommends DCCT's A1C formula to convert A1C to BS. Additionally, our website visitors have preferred DCCT over ADAG formula.
