A home blood
glucose test measures the amount of a type of sugar, called glucose, in your

sugar testing can be used to monitor your blood sugar levels. Talk with your
doctor about how often to check your blood sugar. How often you need to check
it depends on your diabetes treatment, how well your diabetes is controlled,
and your overall health. People who take
insulin to control their diabetes may need to check
their blood sugar level often. Testing blood sugar at home is
often called home blood sugar monitoring or self-testing.
If you use insulin rarely or don't use it at all, blood sugar testing can be very helpful in learning how your body reacts to foods, illness, stress, exercise, medicines, and other activities. Testing before and after eating can help you adjust what you eat.
types of glucose meters can store hundreds of glucose readings. This allows you
to review collected glucose readings over time and to predict glucose levels at
certain times of the day. It also allows you to quickly spot any major changes
in your glucose levels. Some of these systems also allow information to be
saved to a computer so that it can be turned into a graph or another easily
Some newer models of home glucose meters can
communicate with insulin pumps. Insulin pumps are machines that deliver insulin
through the day. The meter helps to decide how much insulin you need to keep
your blood sugar level in your target

A home blood sugar test involves
pricking your finger, palm, or forearm with a small needle (lancet) to collect
a drop of blood and placing the blood on a special test strip, which you insert
into the blood glucose meter before you begin the test. The blood glucose meter
displays the results of a blood sugar test within a minute after
The instructions for testing are slightly different for
each model of home blood glucose meter. For accurate results, follow the
instructions for your meter carefully. When testing blood sugar using a home
blood glucose meter:
Safely dispose of your lancets after using them. Do not
throw them into the household trash. A used lancet might accidentally stick
someone. Place used lancets into a plastic container, such as an empty
detergent bottle. Seal the container when it is about three-quarters full.
Check with your local trash disposal agency about the proper disposal of

The American Diabetes
Association (ADA) recommends that you stay within the following blood sugar
level ranges. But, depending on your health, you and your doctor may set a
different range for you.
Many conditions can change blood
glucose levels. Your doctor will discuss any significant abnormal results with
you in relation to your symptoms and past health.
Reasons you may not be able to
have the test or why the results may not be helpful include:
Proper care of the blood sugar testing equipment is
important to ensure safety and to get accurate results.
