How To Calculate Your A1c
The Hemoglobin A1c test is a blood test used to measure the average blood glucose concentration in your body in the past 1-3 months. For diabetics, this is the standard way of determining how well the diabetes is controlled. An A1c of less than 7% is considered good. Getting the test every 3 months is usually enough. But sometimes you may want to just estimate your A1c level based on the data from your regular self-tests. The formula below could help in this case. Accuracy, of course, could vary depending on how often and when you check your blood sugar. I found it pretty accurate last time I used it. My calculation was off only by 0.1%. This is the same formula GlucoseTracker uses in the app’s dashboard. Glucose in mg/dL: A1c = / 28.7 Glucose in mmol/L: A1c = / 1.59 So, for example, if your average blood glucose level in the past 3 months is 130 mg/dL , your estimated A1c is 6.15%. There are also cheaper devices you can buy that will allow you to do the actual A1c tests yourself, like this one. If you need to do these tests more often, say every month, then it could save you money in the long run as lab tests could get expensive. It may not be as accurate as the lab tests, but my guess is it’s probably good enough.Continue reading > >

Whats The Difference Between A1c And Blood Glucose Levels
February 27, 2018 by Diabetes Care
Checking your A1C as well as your blood glucose levels are things youll do when you have diabetes. Thats because they are both key markers in determining whether your blood sugar levels are within the ideal target range to keep you healthy. So whats the difference between your A1C and blood glucose level? Heres a closer look at what each one means in relation to managing your diabetes.
Whats A Glycated Hemoglobin Test
A glycated hemoglobin test measures the amount of glucose in your blood. The test is often called A1c, or sometimes HbA1c. Its a simple blood test used to:
- Detect prediabetes high sugar levels that can lead to diabetes, heart disease and stroke.
- Diagnose diabetes.
- Tell how well a person with diabetes has been managing the disease.

How Does The A1c Test Work
The hemoglobin A1C test is based on the attachment of glucose to hemoglobin, which is the protein in red blood cells that carries oxygen. In the body, red blood cells are constantly forming and dying, but they live for about three months. Thus, the test reflects the average of a persons blood glucose levels over the past three months. The A1C test result is reported as a percentage.

How To Lower A1c Level
Your doctor will tell you to lower your A1C levels if your test shows they are too high. Here are a few pointers to get you started:
- Consult your doctor about medicine. Make sure youre following the doctors instructions when taking them. Mention any other medications youre taking for different ailments, as they could interact.
- Check your blood sugar levels more frequently and make sure youre using the suitable treatments . If you believe this is a problem for you, seek professional treatment.
- Increase your physical activity. You dont have to train to be an Olympic athlete, but you should strive to include a few short walks in your daily routine. Every step is crucial!
- Attempt to reach and maintain a healthy BMI .
- The BMI is the most fundamental indicator, but you should also consider your waist-hip ratio. A large amount of visceral fat has been related to an increased risk of diabetes and heart disease.
- Maintain a healthy, well-balanced diet. If youre overweight, dont go over your daily calorie restriction, and attempt to eat even less. Say goodbye to processed meals and sweets.
If you follow those recommendations, your hemoglobin A1C levels will almost certainly improve.
Who Should Get An A1c Test And When
Testing for diabetes or prediabetes:Get a baseline A1C test if youre an adult over age 45or if youre under 45, are overweight, and have one or more risk factors for prediabetes or type 2 diabetes:
- If your result is normal but youre over 45, have risk factors, or have ever had gestational diabetes, repeat the A1C test every 3 years.
- If your result shows you have prediabetes, talk to your doctor about taking steps now to improve your health and lower your risk for type 2 diabetes. Repeat the A1C test as often as your doctor recommends, usually every 1 to 2 years.
- If you dont have symptoms but your result shows you have prediabetes or diabetes, get a second test on a different day to confirm the result.
- If your test shows you have diabetes, ask your doctor to refer you to diabetes self-management education and support services so you can have the best start in managing your diabetes.
Managing diabetes:If you have diabetes, get an A1C test at least twice a year, more often if your medicine changes or if you have other health conditions. Talk to your doctor about how often is right for you.

Why Do We Test A1c
Also called hemoglobin a1c or Hba1c, an A1C test is often used to diagnose diabetes initially and then to ensure youre keeping your blood sugar levels in check over an extended period of time. Given that the average red blood cell lives for several months, this test determines your average blood sugar levels over a two- to three-month period.
Recording Your A1c Level:
Its important to keep a record of your blood glucose levels, so that you can see how your diabetes management plan is working over the course of your diabetes journey. There are logbooks available where you can write down your A1C and your blood glucose levels at regular intervals. There are also apps and online tools that can help you record your results quickly and easily.

Application To The Real World
The GMI provides a clue as to what your next A1C result might be, but dont be surprised if they arent a perfect match. The good news is that most people had results within 0.5 percentage points, meaning the two values should still be somewhat close. The GMI may actually be more reflective of true average glucose since there is not any lab interference. Many healthcare offices have been relying on GMI more during COVID-19 when its been challenging to get the lab test.
While A1C and GMI provide a measure of how your glucose management is working, keep in mind that both are just averages. Try focusing on your Time in Range, a metric you can compare day-to-day and week-to-week. If you can increase your TIR, especially focusing on a TIR of 70% or greater, your GMI and A1C are much more likely to also reach their targets. However, if you dont reach your A1C and GMI goals, please dont be disappointed. Its possible to lower A1C and GMI by having tons of hypoglycemia, but this is not good for short-term or long-term health outcomes. If you focus on that Time in Range, you are more likely to feel good and have great diabetes outcomes.
This article is part of a series on Time in Range. The diaTribe Foundation, in concert with the Time in Range Coalition, is committed to helping people with diabetes and their caregivers understand Time in Range to maximize patients’ health. Learn more about the Time in Range Coalition here.
Can The A1c Test Result In A Different Diagnosis Than The Blood Glucose Tests
Yes. In some people, a blood glucose test may show diabetes when an A1C test does not. The reverse can also occuran A1C test may indicate diabetes even though a blood glucose test does not. Because of these differences in test results, health care professionals repeat tests before making a diagnosis.
People with differing test results may be in an early stage of the disease, when blood glucose levels have not risen high enough to show up on every test. In this case, health care professionals may choose to follow the person closely and repeat the test in several months.

Difference Between A1c And Glucose
February 11, 2020 Posted by Dr.Samanthi
The key difference between A1c and glucose is that A1c is the percentage of glycated hemoglobin in the blood, while glucose test is a fasting blood sugar test which is done by a glucometer.
The presence of glucose in the urine is an indication of diabetes. Measuring blood sugar can tell you whether you have prediabetes or type 2 diabetes. Prediabetes is the first stage of type 2 diabetes. Both prediabetes and type 2 diabetes are risky and can cause cardiovascular diseases too. In both cases, blood sugar levels are higher than the normal blood sugar level. There are different tests we can undergo in order to determine high blood sugar. A1c and blood glucose testing are two tests among them.
Average From A Glucose Meter
Although an A1C level gives you a sense of average glucose levels over the past few months, a person with type 1 or type 2 diabetes needs a blood glucose meter to check blood sugar and make treatment decisions on a day-to-day basis.
If you test often during the day like before and after meals and other times that your blood sugar can vary and use an accurate glucose meter, this can give you valuable information on daily variations in blood sugar levels. Many blood glucose meters are also equipped to provide 7, 14, 30, or 90-day averages. A 90-day average on your meter can be used in the calculator above to estimate how it may correlate to an A1C.
Glucose meter averages are based on the frequency that you have tested per day, so if you do not have many data points or are unable to test at certain times , it probably wont give you a full picture of your blood sugar levels and may skew lower than an A1C test result.

What Could Cause A1c To Get Obstructed
Conditions like acute and chronic blood loss, hemolytic anemia, and splenomegaly can cause A1C values that are artificially low. The A1c readings of patients with end-stage renal illness are frequently artificially low. This is because of the chronic anemia that comes with it, which reduces red cell survival.
What Is An A1c Test
The hemoglobin A1c test tells you your average level of blood sugar over the past 2 to 3 months. It’s also called HbA1c, glycated hemoglobin test, and glycohemoglobin. Itâs a lot like a baseball player’s season batting average. A single game doesn’t tell you how a player is performing in their career. And 1 day’s test results don’t give you the complete picture of how your treatment is working.
People who have diabetes need this test regularly to see if their levels are staying within range. It can tell if you need to adjust your diabetes medicines. The A1c test is also used to diagnose diabetes.

Small Changes In Temperature Equipment Or Sample Handling
Even when the same blood sample is repeatedly measured in the same lab, the results may vary because of small changes in temperature, equipment, or sample handling. These factors tend to affect glucose measurementsfasting and OGTTmore than the A1C test.
Health care professionals understand these variations and repeat lab tests for confirmation. Diabetes develops over time, so even with variations in test results, health care professionals can tell when overall blood glucose levels are becoming too high.
What Is The Difference Between My A1c And The Numbers On My Glucometer
When your doctor says you have prediabetes or type 2 diabetes, its usually because of your A1c test result. If your A1c is over 5.7 but below 6.4, you like have prediabetes. If its over 6.5 on two or more tests, you likely have type 2 diabetes.
You will get a glucometer with your first prescription of test strips and fingersticks. The doctor will tell you to aim for readings between 80 and 130 before a meal and under 180 after a meal. And if you are like most people, you will wonder how to make sense of all this new information.

Finally: A1c Is Also Defined As Estimated Average Glucose Or Eag
Another term you may come across when finding out your A1C is eAG. Your doctor might report your A1C results as eAG. eAG is similar to what you see when monitoring your blood sugar at home on your meter. However, because you are more likely to check your blood sugar in the morning and before meals, your meter readings will likely be lower than your eAG.
How Often Should I Have An A1c Test
Diabetes Canada recommends that people with diabetes should have a hemoglobin A1C test every six months, if their blood glucose levels are within target ranges. If blood glucose targets are not currently being met, or people are making changes to your diabetes management , they should have an A1C test every three months.

The Difference Between Eag/a1c And The Average On Your Monitor
The catch is that eAG/A1C is not the same average glucose level as the average of the readings on your meter.
Monitoring measures your blood glucose at a moment in time, whereas eAG/A1C represent an average of your glucose levels 24 hours a day, including times when people are less likely to check their blood sugar .
People with diabetes are also more likely to check their blood glucose more often when they are low , so the average of readings on their meter is likely to be lower than their eAG.
Oral Glucose Tolerance Test
The oral glucose tolerance test takes a little more time than the other two glucose tests for diabetes. In this test, your blood is taken after an overnight fast, and then again two hours after you drink a sugary drink.
Its normal for blood sugar to rise after the drink. Normal blood sugar falls to below 140 mg/dL within two hours, however.
If your blood sugar is between 140 and 199 mg/dL, your doctor will diagnose prediabetes. Anything 200 mg/dL or above is diagnostic for type 2 diabetes.

You should have healthy fats each day as well.
Using the information from your food log, you can begin to make small changes. The goal is to choose less processed, whole foods, instead of highly processed foods that contain added sugar, little fiber, and unhealthy fats.
For example, if you arent eating the recommended servings of vegetables, try adding one serving of vegetables a day to your diet.
You can do this by having a salad with lunch or dinner, or snacking on carrot sticks. Just be careful about add-ons such as salad dressing or dips. They can sneak in unhealthy fats or extra calories. Check out these 10 healthy salad dressing recipes.
Youll also want to work on reducing the number of empty-calorie foods and beverages youre consuming, as well as switching out simple carbohydrate foods for complex carbohydrates. Examples of substitutions you can try to include:
