How Often Should You Have An A1c Lab Test
Your healthcare provider may order an A1C test every three months to monitor diabetes treatment changes, such as adjustments to medications, insulin pump settings, or other areas of diabetes self-management. If your blood glucose is within range and stable, your healthcare provider may only order the test every six months.
If you have not been diagnosed with diabetes, sometimes A1C is used along with other measures to help diagnose diabetes. It may also be used as a baseline measurement for people with a strong family history of diabetes or other risk factors to see if levels are increasing over time.
Some Of The Ways Medicines Can Lower A1c Include:
- cause the liver to reduce its output of glucose
- adding insulin when the body is not producing a sufficient quantity
- reducing insulin resistance by making the body more sensitive to it’s own insulin
- cause the body to increase production of insulin
Keep in mind that illness or infection can also affect A1C. Be sure to make a note of any illnesses you may have had so you can offer your health care provider this information at your next visit.
Understanding The Range Of A1c
If your estimated range falls anywhere above 5.7%, get ahead of the risk early. Take control of your health and start monitoring your glucose more closely with a CGM.

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.

Remember, you only see a rough estimate when calculating your A1C without using a proper lab test. Any calculator will use your blood glucose to estimate your A1C. As you now know, this is only a derivation and not an actual measurement.
A1c Levels Explanation And A1c Calculator
Your A1C test result can be a good general gauge of your diabetes control, because it provides an average blood glucose level over the past few months.
Unlike daily blood glucose test results, which are reported as mg/dL, A1C is reported as a percentage. This can make it difficult to understand the relationship between the two. For example, if you check blood glucose 100 times in a month, and your average result is 190 mg/dL this would lead to an A1C of approximately 8.2%, which is above the target of 7% or lower recommended by the American Diabetes Association for many adults who are not pregnant. For some people, a tighter goal of 6.5% may be appropriate, and for others, a less stringent goal such as 8% may be better.1 Talk to your doctor about the right goal for you.

Bottom Line About Average Blood Glucose And A1c
Your average blood glucose is not really intended to predict your A1C. Rather, A1C is supposed to provide a way to estimate your average blood glucose over time. Any A1C-based prediction may be off by as much as 20 to 25 mg/dL. For some people, it may make more sense to base diabetes treatment decisions off of their BG meter average than their laboratory-measured A1C.

What Does A1c Measure
You may be wondering what makes this test different, especially if you already check your blood sugar multiple times a day. The A1C test goes by a few names, including glycosylated hemoglobin, glycated hemoglobin, or hemoglobin A1C . All of these names hint at what is being measured the amount of sugar attached to hemoglobin.
Hemoglobin is a protein found inside red blood cells, and its job is to carry oxygen to the lungs and all of the cells in your body. Glucose enters your blood stream and sticks, or glycates, with the hemoglobin. The higher your blood glucose, the more sugar-coated or glycated the hemoglobin becomes.
Since the lifecycle of a red blood cell is about four months, the A1C percentage reflects average blood sugar levels detected on hemoglobin cells of varying ages days, weeks, or months old. If your blood glucose control has generally been steady, your hemoglobin cells will not be highly sugar-coated, or glycated, leading to a lower A1C value.
Is The A1c Test Accurate For Everyone
Since the A1C test has been made available , is has become a common way to measure glucose control. However, in the last several years some questions have been raised about potential limitations of A1C:
- Is the A1C accurate for everyone?
- It may not be accurate for some people, including people of African-American descent, people with liver and kidney disease, or with some anemias and sickle cell disease.

What Can I Learn From Converting My Hba1c To Average Blood Glucose Level
Converting your lab test HbA1c to average blood glucose level can be useful to compare your own average blood glucose results.
If, for example, your own average blood glucose results are lower than the average provided by the calculator, this suggests you may not be testing during periods of the day when your blood glucose levels are higher, which could include after meals.
You may therefore wish to carry out more blood glucose testing at different times of day to see if you are experiencing high results that you may not otherwise be aware of.
Conversion From Old Units To New Units
In the past 15 years, to report the results from the glycated hemoglobin test a new unit has been proposed and introduced . Some countries already adopted the new unit in their lab reports, while others still stick to the old unit or use both.
While the results reported are the same, the numbers differ substantially and can create confusion. Here below you can find the conversion table from NGSP to IFCC units.

What Changes They Have Made To The A1c Guidelines
For most adults, the American Diabetes Association currently recommends an A1C of less than 7%, a TIR of over 70%, and a time below the range of less than 4%. In past years, the Standards of Care contained an A1C Testing section that advised diabetics to test their A1C two to four times a year with an A1C target of less than 7%.
What Does The A1c Test Measure
The A1C test measures the average glucose level over the past three months. Think of it as a 24/7 video of all of the ups, downs and in between of glucose levels. It gives you an idea of how well your body is managing glucose.
The A1C test is different than a blood glucose monitor check or continuous glucose monitors. These devices give you the glucose level at that exact moment in time.
Using A1C, along with day-to-day glucose results is a good way of measuring how well diabetes is being managed.

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.
Why Doesn’t My Average Blood Glucose Match My A1c
So, you test your meter for accuracy and everything looks good. You take your average blood glucose and convert it to A1C using a table, calculator, or equation you find online. Then, you get your blood work done and learn that your actual A1C is not even close.
What is the deal? It turns out, the relationship between average BG and A1C isn’t as clear as most of us think.
After doing some research, I came across a couple of reasons why someone’s actual A1C may be higher or lower than expected.

Understanding Your A1c Conversion Result
The ADA recommends that your hemoglobin A1C be below 6.5 percent. However, there may be exceptions to this. For instance, some people have other medical conditions that cause their hemoglobin A1C readings to go above 6.5 percent regularly. Others may have anemia or another health condition that makes hemoglobin A1C readings less useful, according to Cox. Talk to your doctor about the right target number for you.
In addition to understanding a higher A1C number, it’s also important to monitor low A1C trends. For example, if your A1C has consistently been about 8 percent and it’s now closer to 7 percent, this could be due to better diabetes care. However, it also could indicate you are having blood sugar readings that are too low. This is something you’ll want to problem-solve with your care team, Cox says.
As always, knowing these numbers is not a replacement for medical care. Talk to your doctor about any results you don’t understand, and share your results with everyone on your diabetes care team.
