An A1C studying might be useful when you perceive what it means about your each 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 essential a part of diabetes administration.
On this article, we’ll talk about 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 end result 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 proportion of glycated hemoglobin, or HbA1c, in your blood. Glycated hemoglobin types when glucose within the bloodstream attaches to the hemoglobin in purple blood cells.
The upper the glucose ranges within the bloodstream, the extra that attaches to the purple blood cell, thus the upper the A1c.
This course of displays the common blood glucose ranges over the previous 2 to three months, offering data in your glucose management.
It’s necessary to know that whereas A1c offers a direct measure of glycated hemoglobin, constantly excessive A1c ranges counsel extended publicity to excessive glucose ranges, which can enhance the chance of forming AGEs within the physique.
These compounds can contribute to the blood vessel and nerve harm related to the issues of diabetes, resembling retinopathy (eye harm), neuropathy (nerve harm), and nephropathy (kidney harm).
Accordingly, constantly excessive blood glucose ranges can result in elevated formation of AGEs, which in flip can contribute to diabetes-related issues.
Nevertheless, it’s necessary 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’d like that can assist you perceive one factor: your eAG.
Your eAG represents the common 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 big position when you’re aiming to enhance your A1c and decrease the chance of diabetes issues.
It’s necessary to know that blood sugar ranges naturally fluctuate all through the day on account of varied components resembling what you eat, exercise, and stress. Due to this fact, eAG just isn’t a hard and fast quantity that your blood glucose ranges adhere to always.
As a substitute, consider eAG as an general common that smooths out these each day ups and downs to offer a extra complete image of your glucose management over time. This common is a great tool for assessing how effectively your diabetes administration plan is working and making essential 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 % may lead some to consider their glucose ranges are constantly 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 may 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 larger 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 might be stunning 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 each day readings can present. This extra perspective is useful for making knowledgeable changes to your diabetes care plan.
You should utilize this straightforward eAG/A1c conversion chart from the American Diabetes Affiliation (ADA) to immediately translate your newest A1c end result 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 |
Normally, 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 folks with diabetes.

Figuring out your individual A1c and eAG objectives
In a perfect world, our A1cs would all be a magical 5.0. However managing diabetes might be difficult.
Because of this figuring out the precise A1c aim for you, your physique, and your life as an individual with diabetes is a really private determination that you just and your healthcare crew should work collectively to determine on.
For example, somebody with a historical past of hypoglycemia unawareness (the lack to detect the early indicators of low blood glucose) might discover a goal A1c of 6.0 % to be too harmful, placing them at an excessive amount of threat for extreme hypoglycemia.
Somebody who lives by themselves might discover that sleeping with blood sugars decrease than 120 mg/dL, for instance, places them at larger threat for hypoglycemia.
For individuals who have been working blood glucose ranges larger than 240 mg/dL, the aim could also be to steadily decrease their blood glucose ranges with the assistance of their healthcare crew.
This implies their A1c goes to be set at a better goal than “regular,” too.
No matter your blood sugar targets, they need to be periodically reviewed and adjusted, as essential, in collaboration together with your healthcare crew to replicate any modifications in your well being standing, life-style, or diabetes administration wants.
To be taught extra about setting and reaching reasonable A1c objectives, you may watch this video the place Christel Oerum, the founding father of Diabetes Sturdy, explains how she retains her A1c at her goal vary by following 5 easy steps:
How usually ought to you’ve gotten an A1c take a look at?
If you’re residing with diabetes, your healthcare supplier might order an A1c take a look at for you someplace between two and 4 occasions a 12 months, relying on components resembling your stage of blood sugar administration and frequency of extreme hypoglycemia (low blood sugar) or hyperglycemia (excessive blood sugar).

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