Glucose (Gluc)




Glucose is the primary energy source for the body’s cells and the only energy source for the brain and nervous system. A steady supply must be available for use, and a relatively constant level of glucose must be maintained in the blood.

Several health organizations, including the American Diabetes Association (ADA) and the U. S. Preventive Services Task Force (USPSTF), recommend diabetes screening when a person is 45 years of age or older or when a person of any age has risk factors. Examples of risk factors include:

  • History of cardiovascular disease (CVD)
  • Overweight, obese, or physically inactive
  • A close (first degree) relative with diabetes
  • A woman who delivered a baby weighing more than 9 pounds or with a history of gestational diabetes
  • A woman with polycystic ovarian syndrome
  • High-risk race or ethnicity such as African American, Latino, Native American, Asian American, Pacific Islander
  • High blood pressure (hypertension) or taking medication for high blood pressure
  • Low HDL cholesterol level (less than 35 mg/dL or 0.90 mmol/L) and/or a high triglyceride level (more than 250 mg/dL or 2.82 mmol/L)
  • A1c equal to or above 5.7%
  • Prediabetes identified by previous testing

Requirements: Fasting required (Please consult your physician). To fast for blood work, do not eat anything for 8 to 12 hours before the test. It’s best to schedule fasting blood work for the morning, so that you don’t have to spend the whole day hungry. If fasting is not done before blood work, the results of the blood tests may be inaccurate.
