Have you heard of the A1c test? The A1c is the primary test used to manage diabetes.[1] Diabetes impacts about 37 million Americans in the United States.[2] You could be one of the millions of people across the nation that have diabetes or have just been diagnosed with the chronic condition. If that’s you, it is essential to understand the A1c, ways to manage your glucose level, and how much you can lower your A1c in a month.
The A1c is a blood test that measures your average blood glucose or sugar levels for a period of 3 months.[1,3] The test is also known as the hemoglobin A1c or HbA1c test. The glucose in your bloodstream attaches to a protein called hemoglobin in your red blood cells. The A1c test shows the percentage of red blood cells having hemoglobin coated with glucose. Higher glucose levels in the blood translate to more glucose-attached hemoglobin, leading to an increased A1c result.
The A1c test can be done in a lab with a traditional blood draw, a fingerstick in your doctor’s office, or an A1c at-home lab test.[3] You do not have to fast before taking the A1c, and it can be completed anytime during the day.[4]
When you get your A1c results back, what do the numbers mean? When using the A1c test for a diagnosis of diabetes, the levels are as follows[1,4]:
For a diagnosis of diabetes, you will typically receive a second test to confirm the result.[1,4] The A1c test is only used to diagnose type 2 diabetes.
Keeping your glucose levels in your target range as often as possible can help prevent or delay severe chronic health conditions like heart disease, vision loss, and kidney issues.[1,5] To keep your glucose at healthy levels, your healthcare provider may recommend that you [5]:
The target A1c goal for most diabetic adults is around 7% to 8%, but the range can vary slightly depending on age, other health conditions, medications, and other factors.[1,5] Speak with your healthcare provider to determine your individualized A1c goal. If you are struggling to lower your A1c, be sure to discuss it with your healthcare provider. Methods for lowering your A1c include [5]:
The A1c test is the average of your blood glucose levels for a period of three months.[1,3] If you’re wondering how much can you lower your A1c in a month, don’t anticipate immediate results. This is because red blood cells have a lifespan of about three months. After a few months of lifestyle changes, you’ll gradually be able to see your A1c go down. But you probably won’t see a lower A1c until after about three months of changes. Don’t be discouraged after a month.
If you are struggling to maintain your target range A1c level, be sure to speak with your healthcare provider. Everlywell offers an at-home HbA1c test to measure and assess your A1c level from the comfort of your own home. Your test result will show your average blood glucose level for the past three months.
