Know Your Blood Sugar Numbers
Taking control of your diabetes can help you feel better and stay healthy. Lowering your blood sugar (also called blood glucose) by any amount reduces your chances of having eye, kidney, and nerve problems. Knowing your blood sugar numbers will help you control your diabetes.
There are two different tests to measure your blood sugar:
You need both tests to get a complete picture of your blood sugar control.
The Hemoglobin A1c Test
What is the hemoglobin A1c test?
The hemoglobin A1c test (also called H-B-A-one-C or A-1-C) is a simple lab test that shows how well you have controlled your blood sugar over the last 3 months.
Why should I have a hemoglobin A1c test?
The hemoglobin A1c test is the best test for you and your health care provider to know if your blood sugar is under control. This test shows if your blood sugar has been close to normal or too high.
How often do I need this test?
Ask your health care provider for a hemoglobin A1c test at least twice a year. Get the test more often if your blood sugar stays too high or if your treatment plan changes.
What about home testing for hemoglobin A1c?
Home testing for hemoglobin A1c is now possible and some people with diabetes may find it helpful to use this test. Be sure to follow the instructions and discuss your results with your health care provider.
Testing Your Own Blood Sugar
Why should I do this test?
Self-testing helps you see how food, physical activity, and diabetes medicine affect your blood sugar. The readings you get from these tests can help you manage your diabetes day by day or even hour by hour. Keep a record of your test results and review it with your health care provider.
How do I test my own blood sugar?
Use a drop of blood and a meter to measure how much sugar is in your blood. This simple test tells you what your blood sugar is at the time you test.
What is a good self-testing blood sugar goal?
Set your goals with your health care provider. Ideal goals for most people with diabetes when self-testing are:
Before Meals 80-130 mg/dl
At Bedtime 100-150 mg/dl
Your blood sugar goals may be different from these ideal goals. Ask your health care provider what goals are best for you.
How often should I do this test?
Self-tests are usually done before meals and/or at bedtime. Ask your health care provider when and how often you need to test your blood sugar.
If I test my own blood sugar, do I still need the hemoglobin A1c test?
Yes. The results of each test help you and your health care provider to manage your diabetes. You need both tests to get a complete picture of your blood sugar control.
What is a good hemoglobin A1c goal?
The hemoglobin A1c goal for most people with diabetes is less than 7 percent. If your number is less than 7 percent, your treatment plan is probably working and it is likely that your blood sugar is under good control. A hemoglobin A1c number higher than 8 percent means that you have a greater chance of getting eye disease, kidney disease, or nerve damage. Any lowering of the hemoglobin A1c number toward your goal can help reduce your chances of getting these problems. If your number is higher than 8 percent, ask your health care provider how you can bring your number down.
