Glucose Test - part of the Comprehensive Metabolic Panel

A blood glucose test measures the amount of a sugar called glucose in a sample of your blood.

Glucose is a major source of energy for most cells of the body, including brain cells. Carbohydrates are found in fruit, cereal, bread, pasta, and rice. They are quickly turned into glucose in your body, raising your blood glucose level.

Insulin and other chemicals in the body help control blood glucose level.

This test is part of Cardio-Med's complete physical exam.

If you have any of the risk factors below, ask your physician about getting tested at an earlier age and more often:

Children age 10 and older who are overweight and have at least 2 of the risk factors listed above should be tested for type 2 diabetes every 3 years, even if they have no symptoms.

Normal Results

If you had a fasting blood glucose test, a level between 70 and 100 mg/dL is considered normal.

If you had a random blood glucose test, a normal result depends on when you last ate. Most of the time, the blood glucose level will be below 125 mg/dL.

What Abnormal Results Mean

If you had a random blood glucose test:

Other medical problems can also cause a higher-than-normal blood glucose level, including:
