An A1C studying will be useful when you perceive what it means about your every 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 degree is a vital 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 kind Superior Glycation Finish-products (AGEs), how your A1c consequence interprets to an estimated common glucose (eAG), and what you are able to do with that info.

What your A1c is absolutely 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 crimson blood cells.
The upper the glucose ranges within the bloodstream, the extra that attaches to the crimson blood cell, thus the upper the A1c.
This course of displays the common blood glucose ranges over the previous 2 to three months, offering info in your glucose management.
It’s necessary to know that whereas A1c gives a direct measure of glycated hemoglobin, constantly excessive A1c ranges counsel extended publicity to excessive glucose ranges, which can improve the chance of forming AGEs within the physique.
These compounds can contribute to the blood vessel and nerve injury related to the problems of diabetes, resembling retinopathy (eye injury), neuropathy (nerve injury), and nephropathy (kidney injury).
Accordingly, constantly excessive blood glucose ranges can result in elevated formation of AGEs, which in flip can contribute to diabetes-related problems.
Nevertheless, it’s necessary to notice that the A1c check particularly measures the quantity of glucose that has hooked up to hemoglobin, serving as an oblique indicator of common blood glucose ranges and potential for AGE-related injury over time.
What’s an estimated common glucose degree?
Earlier than we begin speaking about A1c outcomes, we want that can assist you perceive one factor: your eAG.
Your eAG represents the common blood sugar degree over a interval, sometimes mirroring the timeframe of the A1c.
Though you won’t hear the time period eAG incessantly in your physician’s workplace, it performs a big position when you’re aiming to enhance your A1c and reduce the chance of diabetes problems.
It’s necessary to know that blood sugar ranges naturally fluctuate all through the day because of varied elements resembling what you eat, exercise, and stress. Due to this fact, eAG will not be a hard and fast quantity that your blood glucose ranges adhere to always.
As an alternative, consider eAG as an general common that smooths out these every 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 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 degree
Seeing an A1c results of, say, 8.0 % would possibly 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 would possibly reveal a special 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 every day readings can present. This extra perspective is useful for making knowledgeable changes to your diabetes care plan.
You should use this easy eAG/A1c conversion chart from the American Diabetes Affiliation (ADA) to immediately translate your newest A1c consequence 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 degree of 80 to 130 mg/dL (4.4 to 7.2 mmol/L), a blood sugar degree 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 objectives
In a super world, our A1cs would all be a magical 5.0. However managing diabetes will be difficult.
Because of this figuring out the fitting A1c objective for you, your physique, and your life as an individual with diabetes is a really private determination that you just and your healthcare workforce should work collectively to resolve on.
As an illustration, 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 danger 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 greater danger for hypoglycemia.
For individuals who have been operating blood glucose ranges greater than 240 mg/dL, the objective could also be to progressively decrease their blood glucose ranges with the assistance of their healthcare workforce.
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 essential, in collaboration together with your healthcare workforce to mirror any modifications in your well being standing, life-style, or diabetes administration wants.

How typically ought to you will have an A1c check?
If you’re dwelling with diabetes, your healthcare supplier might order an A1c check for you someplace between two and 4 occasions a yr, relying on elements resembling your degree of blood sugar administration and frequency of extreme hypoglycemia (low blood sugar) or hyperglycemia (excessive blood sugar).

Remaining ideas
Everyone seems to be in a special place with their diabetes administration, and all of us have totally different private wants, challenges, and objectives. And that’s OK. Work carefully together with your healthcare workforce, and give attention to what’s best for you and your present life as an individual with diabetes.
