Home Blood Glucose Test
A home blood
glucose test measures the amount of a type of sugar, called glucose, in your
blood at the time of testing. The test can be done at home or anywhere, using a
small portable machine called a blood glucose meter.
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 several times a day. Testing blood sugar at home is
often called home blood sugar monitoring or self-testing.
If you are using an insulin pump or if you use insulin more than once a day, the American Diabetes Association (ADA) recommends testing your blood sugar 3 or more times every day.1 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
Why It Is Done
A home blood glucose test is an
accurate way to measure your blood sugar level at the time of testing. If you
have diabetes, testing your blood glucose levels at home provides information
- Your blood sugar level. It is important to know
when your blood sugar is high or low, to prevent emergency situations from
developing. It is also important to treat consistently high blood sugar levels
so you can decrease your chances of developing heart, blood vessel, and nerve
complications from diabetes.
- How much insulin to take before each
meal. If you take rapid-acting or short-acting insulin before meals, the blood
sugar test results can help you determine how much insulin to take before each
meal. If your blood sugar level is high, you may need extra insulin. If your
blood sugar level is low, you may need to eat before you take any
- How exercise, diet, stress, and being ill affect your
blood sugar levels. Testing your blood sugar can help you learn how your body responds to these things. Where possible, you can adjust your lifestyle to improve your blood sugar level.
Home blood sugar testing also may be used to:
- Decide on an initial insulin dose and schedule
or to adjust the insulin doses or schedule.
- Test blood sugar levels
in people who have symptoms of high blood sugar (hyperglycemia) or
low blood sugar (hypoglycemia).
