When your older family member is tested for high blood sugar, you may hear the doctor refer to the results of the test as A1C or eAG. If the older adult has seen more than one doctor, you may have even heard both terms used. That could leave you wondering if there’s a difference between the two and, if so, what is it?

Home Health Care in Johns Creek GA: Difference Between eAG and A1C


What is A1C?

The A1C blood test is used to determine how well blood glucose has been controlled over the last few months. It is used to test for diabetes and to see how well a person’s diabetes treatment is working. To determine A1C the test measures the amount of glucose that is attached to hemoglobin, which is a protein found in red blood cells. Red blood cells live in the bloodstream for about 4 months, so by measuring glucose attached to blood cells, doctors are able to determine an average blood glucose level.

Because daily blood glucose readings can vary based on the activity a person engages in and the foods they eat, an A1C test gives doctors a more accurate idea of how well treatment is working. It also helps to determine whether the patient’s self-tests have been accurate. In addition, doctors can use the test results to talk to patients about how the lifestyle choices they make affect their blood sugar.

What is eAG?

eAG is very similar to A1C in that it offers an average reading of blood sugar. However, it is often easier for people with diabetes to understand because the results are reported in the same way blood sugar monitors report the results of tests taken at home.

A1C reports the percentage of red blood cells that have glucose attached to them. For most people, it’s hard to figure out how that reading corresponds to what they see on their monitors. Fortunately, researchers determined a way to use the results of the A1C test to calculate an estimated average glucose, or eAG, that looks the same as what patients see on their home monitors.

Regardless of how the results are reported, it’s important that older adults with diabetes know how well their treatment plan is working and what they can do to improve their numbers. Senior care can assist them to take the appropriate steps. A senior care provider can plan and cook healthy meals that follow the eating guidelines suggested by the doctor or dietician. Senior care providers can also increase physical activity in your aging relative by keeping them busy around the house, going for walks with them, or taking them to an exercise class designed for older adults.
