What does estimated average glucose mean in a blood test?

Estimated average glucose (eAG) is an estimated average of your blood sugar (glucose) levels over a period of 2 to 3 months. It is based on your A1C blood test results. Knowing your eAG helps you predict your blood sugar levels over time. It shows how well you are controlling your diabetes.

How do you calculate average glucose from HbA1c?

You can also use the formula directly, using a calculator: 28.7 x HbA1c — 46.7 = eAG (in mg/dl). For example, an HbA1c level of 7% would translate into 28.7 x 7 — 46.7, or roughly 154 mg/dl.

Can you determine A1C from average blood sugar?

What is A1C? Performed by your doctor during your regular visits, your A1C test measures your average blood sugar levels by taking a sample of hemoglobin A1C cells—a component of your red blood cells.

  1. being mindful of portion sizes.
  2. eating regularly, every 3-5 hours.
  3. eating similar sized portions at meals and snacks.
  4. planning meals ahead of time.
  5. keeping a journal of food, medication, and exercise.
  6. spreading out carbohydrate-rich foods throughout the day.

What does it mean if your eAG is high?

What does a high estimated average glucose level mean? A higher than normal EAG indicates that your blood sugar is not being controlled sufficiently. Knowing this will allow your healthcare professional to alter your treatment plan and suggest lifestyle changes to reduce your risk of complications due to diabetes.

This is why there’s really no need to have the test more often than every 3 months. However, if you are newly diagnosed and may have been far out of range for a while, you may want to have your A1C measured every 2 weeks at first. Significant changes in blood glucose can be seen within 2 weeks.

Is an A1C of 7.0 good?

An A1C reading of 7.0 or less indicates that your blood sugar control is probably quite good. Patients who maintain their hemoglobin AIC levels below 7.0 are less at risk for developing the complications of diabetes and are more likely to retain their vision. Hemoglobin AIC readings above 8.0 are not as good.

Can A1C levels fluctuate?

Can HbA1c fluctuate?

Definition of “fluctuations in HbA1C” The main predictor “fluctuations in HbA1C” was defined as an increase in HbA1C of more than 2% between two consecutive measurements (3 months interval ± 2 weeks) or an increase in HbA1C of more than 1% at 2 points in time.

How do you calculate average glucose?

An average is calculated by adding up all the numbers in a set and dividing the sum by the number of numbers in the set. For example, if you checked your blood glucose level 25 times in 14 days, your meter would tally all of your readings and divide the sum by 25 to get your 14-day average.Jan 6, 2016
