What is the blood glucose test?

This test measures the amount of glucose (sugar) in your blood. Sugar is an important source of energy, especially for the brain. The amount of glucose in your blood is carefully controlled by the endocrine (glandular) system. This system causes sugar to be stored or used for energy, depending on the needs of your body.

You can get glucose directly from some foods, such as table sugar. Your body also produces glucose when other foods, such as bread and cereal, are digested.

How is the test done?

Your health care provider may poke your finger with a lancet and fill a small tube with the blood. Or a small amount of blood may be taken from your arm with a needle. The blood is sent to a lab.

Having this test will take just a few minutes of your time. There is no risk of getting AIDS, hepatitis, or any other blood-borne disease from this test.
