An A1C studying will be useful when you perceive what it means about your day by day blood glucose (sugar) ranges.
Understanding how your A1c accumulates over the course of two to three months and the way it interprets to an precise common blood sugar stage is a crucial a part of diabetes administration.
On this article, we’ll focus on the importance of glycated hemoglobin as measured by your A1c, the broader context of how glucose can react with proteins within the physique to type Superior Glycation Finish-products (AGEs), how your A1c outcome interprets to an estimated common glucose (eAG), and what you are able to do with that data.
What your A1c is actually measuring: glycated hemoglobin
Your A1c displays the share of glycated hemoglobin, or HbA1c, in your blood. Glycated hemoglobin kinds when glucose within the bloodstream attaches to the hemoglobin in pink blood cells.
The upper the glucose ranges within the bloodstream, the extra that attaches to the pink blood cell, thus the upper the A1c.
This course of displays the typical blood glucose ranges over the previous 2 to three months, offering data in your glucose management.
It’s essential to grasp that whereas A1c gives a direct measure of glycated hemoglobin, persistently excessive A1c ranges recommend extended publicity to excessive glucose ranges, which can improve the danger of forming AGEs within the physique.
These compounds can contribute to the blood vessel and nerve harm related to the issues of diabetes, reminiscent of retinopathy (eye harm), neuropathy (nerve harm), and nephropathy (kidney harm).
Accordingly, persistently excessive blood glucose ranges can result in elevated formation of AGEs, which in flip can contribute to diabetes-related issues.
Nevertheless, it’s essential to notice that the A1c take a look at particularly measures the quantity of glucose that has connected to hemoglobin, serving as an oblique indicator of common blood glucose ranges and potential for AGE-related harm over time.
What’s an estimated common glucose stage?
Earlier than we begin speaking about A1c outcomes, we want that can assist you perceive one factor: your eAG.
Your eAG represents the typical blood sugar stage over a interval, sometimes mirroring the timeframe of the A1c.
Though you may not hear the time period eAG often in your physician’s workplace, it performs a major function when you’re aiming to enhance your A1c and decrease the danger of diabetes issues.
It’s essential to grasp that blood sugar ranges naturally fluctuate all through the day resulting from numerous elements reminiscent of what you eat, exercise, and stress. Subsequently, eAG isn’t a set quantity that your blood glucose ranges adhere to always.
As a substitute, consider eAG as an general common that smooths out these day by day ups and downs to supply a extra complete image of your glucose management over time. This common is a useful gizmo for assessing how nicely your diabetes administration plan is working and making crucial changes.
Now, let’s dive deeper into how this all ties collectively…
Translating your A1c to a blood sugar stage
Seeing an A1c results of, say, 8.0 % would possibly lead some to imagine their glucose ranges are persistently inside their goal vary. Nevertheless, a deeper look into what an A1c of 8.0 % actually interprets to when it comes to common blood sugar would possibly reveal a unique story.
An A1c of 8.0 % corresponds to an eAG of roughly 183 mg/dL (10.1 mmol/L). This common is considerably greater than the ADA-recommended goal for many non-pregnant adults, which is an eAG of lower than 154 mg/dL (lower than 8.6 mmol/L) or an A1c of lower than 7.0 %.
The discrepancy between an in-the-moment glucose studying and the 3-month common mirrored by A1c will be shocking and highlights the significance of understanding each measures in diabetes administration.
By translating your A1c into an eAG, you acquire a clearer image of your general blood sugar administration, past what day by day readings can present. This extra perspective is useful for making knowledgeable changes to your diabetes care plan.
You need to use this straightforward eAG/A1c conversion chart from the American Diabetes Affiliation (ADA) to immediately translate your newest A1c outcome into extra simply comprehensible eAG outcomes.
A1c to eAG chart
| A1c | eAG (mg/dL) | eAG (mmol/L) |
| 5 % | 97 | 5.4 |
| 6 % | 126 | 7.0 |
| 7 % | 154 | 8.6 |
| 8 % | 183 | 10.2 |
| 9 % | 212 | 11.8 |
| 10 % | 240 | 13.4 |
| 11 % | 269 | 14.9 |
| 12 % | 298 | 16.5 |
Basically, the ADA recommends a fasting blood sugar stage of 80 to 130 mg/dL (4.4 to 7.2 mmol/L), a blood sugar stage 1 to 2 hours after meals of lower than 180 mg/dL (10.0 mmol/L), and an A1c of lower than 7.0 % in individuals with diabetes.

Figuring out your individual A1c and eAG targets
In a perfect world, our A1cs would all be a magical 5.0. However managing diabetes will be difficult.
Which means that figuring out the best A1c objective for you, your physique, and your life as an individual with diabetes is a really private choice that you simply and your healthcare crew should work collectively to resolve on.
As an example, somebody with a historical past of hypoglycemia unawareness (the shortcoming to detect the early indicators of low blood glucose) could discover a goal A1c of 6.0 % to be too harmful, placing them at an excessive amount of danger for extreme hypoglycemia.
Somebody who lives by themselves could discover that sleeping with blood sugars decrease than 120 mg/dL, for instance, places them at greater danger for hypoglycemia.
For individuals who have been working blood glucose ranges greater than 240 mg/dL, the objective could also be to regularly decrease their blood glucose ranges with the assistance of their healthcare crew.
This implies their A1c goes to be set at the next goal than “regular,” too.
No matter your blood sugar targets, they need to be periodically reviewed and adjusted, as crucial, in collaboration along with your healthcare crew to mirror any adjustments in your well being standing, way of life, or diabetes administration wants.
To study extra about setting and reaching reasonable A1c targets, you possibly can watch this video the place Christel Oerum, the founding father of Diabetes Robust, explains how she retains her A1c at her goal vary by following 5 easy steps:
How usually ought to you will have an A1c take a look at?
If you’re residing with diabetes, your healthcare supplier could order an A1c take a look at for you someplace between two and 4 instances a yr, relying on elements reminiscent of your stage of blood sugar administration and frequency of extreme hypoglycemia (low blood sugar) or hyperglycemia (excessive blood sugar).

Ultimate ideas
Everyone seems to be in a unique place with their diabetes administration, and all of us have completely different private wants, challenges, and targets. And that’s OK. Work intently along with your healthcare crew, and concentrate on what’s best for you and your present life as an individual with diabetes.
