Testing Your Blood Sugar
Knowing your blood sugar (also called blood glucose) numbers is important to managing
your diabetes. Keeping track of your blood glucose helps you see how food, physical
activity, and medicine affect your blood glucose levels.
Using a blood glucose meter
Checking your 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 glucose in the drop of blood you provide. Learn
how to check your blood sugar on LevemirCare™.
Blood sugar levels throughout the day
There are 2 different ways for testing blood sugar levels:
- Fasting blood glucose: blood sugar level after not
eating for 8 to 12 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 glucose levels in most non-pregnant adults. Individual goals may vary and 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)
People with diabetes often test blood glucose before and after meals. They may also
check at bedtime. To know more about how often to check your blood glucose, consult
with your doctor.
You should also keep a record of your blood glucose monitor readings and review
them during doctor visits. To get started, use this
blood sugar diary.
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 blood glucose level over the last 3 months.
Level of Control
Less than 7%
7% or more
This chart shows the range of A1C test results. Discuss your A1C test score with
your doctor to find the A1C goal that’s right for you.
For most people with diabetes, an A1C test score 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. Everyone’s needs are unique, so you should talk with your doctor
about how to lower your A1C score. Learn more about
