Blood Glucose Screening

Blood glucose screenings are tests done to:
Screen for diabetes
Monitor the treatment of diabetes
Check for abnormally low blood glucose levels (hypoglycemia)

A blood glucose test measures the amount of a type of sugar, called glucose, in your blood. Glucose comes from carbohydrate (starchy and sugary) foods. It is the main source of energy used in the body. Insulin is a hormone released from the pancreas that helps your body use, control and maintains the proper amount of glucose in your blood.

Normally, your blood glucose levels increase slightly after eating a meal. This increase causes the pancreas to release insulin so blood glucose levels do not get too high. In people with diabetes blood glucose levels remain too high in the blood stream because of many different metabolic abnormalities. When blood glucose levels remain high for extended periods of time and go untreated damage can occur to your heart, eyes, kidneys, nerves and blood vessels.

Blood glucose screening tests are not diagnostic of diabetes. They are simply a test that may indicate further follow-up with your medical provider if the result is above the recommended range. Only your medical provider can diagnose diabetes.
