The importance of testing and recording your blood sugar
Knowing your blood sugar (also called blood glucose) numbers is important to managing your diabetes. Keeping track of your blood sugar helps you see how food, physical activity, and medicine affect your blood sugar levels.
Using a blood glucose meter
Checking blood sugar is important for people with diabetes. A device called a blood glucose meter or blood glucose monitor can give you the information you need. These devices measure the sugar in the drop of blood you provide. Learn more about how to check your blood sugar at cornerstones4care.com.
You can stay aware of your blood sugar trends by recording your blood sugar test results in a diary.

Blood sugar levels throughout the day
There are different times for testing blood sugar levels:
- Fasting blood glucose—blood sugar level after not eating for at least 8 hours (usually overnight)
- Postprandial blood glucose—blood sugar level taken 1 to 2 hours after eating
The readings from your blood glucose meter can help you understand your insulin needs for these different times of the day. The chart below shows the expected range of blood sugar levels in most non-pregnant adults. Individual blood sugar goals may vary. You should talk to your doctor about your goals.
|Fasting blood glucose||70 to 130 (mg/dL)|
|Postprandial blood glucose||Less than 180 (mg/dL)|
|Fasting blood glucose|
|70 to 130 (mg/dL)|
|Postprandial blood glucose|
|Less than 180 (mg/dL)|
In addition to fasting blood glucose checks, people with diabetes often test blood sugar before and after meals. They may also check at bedtime. To know more about how often to check your blood sugar, consult with your doctor.
The A1C Test
An A1C test is a blood sugar test that helps you and your doctor understand how well your treatment plan is working over time. For this test, your doctor will ask you to provide a small blood sample, which will be tested in a lab. The results from the A1C test will show your average blood sugar over the last 3 months.
For many people with diabetes, an A1C of less than 7% is a good goal. If your result is 7% or more, you should talk to your doctor. If you and your doctor agree that your blood sugar levels are not well controlled, you may need to change your treatment plan. Each person with diabetes has unique needs and goals. You should talk with your doctor about how to lower your A1C level.
