This test is performed to identify the glucose level in your blood to detect if you have low blood glucose (hypoglycemia) or high blood glucose (hyperglycemia), and can determine your risk for diabetes or a pre‐diabetic condition.

What is diabetes?

Diabetes is a leading cause of death worldwide, particularly in developed countries. It is estimated that nearly one‐third of all people with diabetes in the U.S. are not even aware they have the disease. Diabetes is caused by the body’s inability to properly process glucose, a form of sugar found in your bloodstream, into energy.

Diabetes risk factors include:

  • Obesity
  • Family history
  • High-risk ethnicity
  • High blood pressure
  • High triglycerides
  • High cholesterol
  • Low HDL
  • Gestational diabetes during pregnancy

What are the symptoms of hyperglycemia?

A person with high blood glucose may exhibit one or more of the following symptoms:

  • Increased thirst
  • Fatigue
  • Blurred vision
  • Slow-healing wounds or infections

What are the symptoms of hypoglycemia?

TEST RESULTS

HOW DO I GET TESTED?

To order your own lab tests, you just need to follow these three easy steps:

  1. Complete a lab order form for your test online and print it out to take with you to the DLO Patient Service Center. Follow the instructions on the laboratory test order form if fasting is required for the testing you are ordering.
  2. Visit any DLO Patient Service Center throughout Oklahoma. Check in with our friendly staff and give them your completed order form. Full payment is due at time of service before sample collection is performed. Note that we accept all major credit cards and checks. Unfortunately, we cannot accept cash payments. Have one of our skilled phlebotomists draw a blood sample or take a urine sample, who will send your sample to our laboratory for testing.
  3. Create a MyQuest™ account and view your test results through the MyQuest online patient portal. Test results are available through MyQuest within 7-10 business days of completing your lab work.

WHAT SHOULD I DO IF MY RESULTS ARE ABNORMAL OR OUT-OF-RANGE?

It is always recommended you meet with a health care provider to determine what your laboratory test results mean to you. Your health care provider will review all of your test results and, combined with your health history, will be able to provide an accurate course of action.

If your results were high: Abnormally high results may indicate that you have impaired fasting glucose (pre‐diabetes) or diabetes.

If your results were low range: Abnormally low results can indicate hypoglycemia.

As with any abnormal results, it’s important that you discuss their implications with your health care provider.
