Why choose Henry Ford Health for diabetes screening?

Because symptoms of diabetes can be mild at first, you may have the condition and not know it. However, chronic high levels of blood glucose (sugar) can cause serious complications that affect the eyes, nerves, heart and other organs. That’s why it’s important for all adults to get screened for diabetes every 3 years beginning at age 45.

People with the following risk factors should begin screening at an earlier age and more regularly than 3 years:

  • Obesity
  • High blood pressure
  • High cholesterol
  • A family history of diabetes
  • In women, a history of gestational diabetes (diabetes during pregnancy)

A potential diagnosis for diabetes can be stressful for you and your family. You can rest assured knowing that expert care is nearby at a Henry Ford. With Diabetes Care Centers throughout southern Michigan, we make it easy for you to get tested for this serious yet manageable condition.

What diabetes screenings do we offer?

We screen for and diagnose diabetes using blood tests that measure your blood sugar levels. The tests include:

  • Fasting plasma glucose (FPG) test

    This test measures your current blood sugar levels after you have fasted for at least 8 hours. We use the FPG test to detect and diagnose prediabetes, type 1, type 2 and gestational diabetes.

    • A normal fasting blood glucose level is 100 mg/dL or lower.
    • Levels between 100 to 125 mg/dL mean that you have prediabetes.
    • A fasting blood glucose level of 126 mg/dL or higher means that you have diabetes.
  • Hemoglobin A1C test for type 2 diabetes

    This test provides information about your blood sugar levels over the past 2 to 3 months. You do not need to fast (stop eating) for the A1C test. We use the A1C test to diagnose type 2 diabetes.

    • The normal range for this test is 4 to 5.6 percent.
    • Levels between 5.7 to 6.4 percent mean that you have prediabetes, which is a higher risk of developing diabetes.
    • An A1C of 6.5 percent or higher indicates type 2 diabetes.
  • Oral glucose tolerance test (OGTT)

    This test measures your blood sugar levels twice, so it takes longer than the other 2 tests. We use the OGTT test to detect prediabetes and diagnose all types of diabetes.

    We first test your blood after you have fasted for at least 8 hours. Then you drink a sugary drink, which causes your blood sugar to rise. We then test your blood sugar after 2 hours to assess how quickly your blood sugar levels return to normal.

    • A normal blood glucose level in the OGTT is 140 mg/dL or lower.
    • Levels between 140 to 199 mg/dL indicate prediabetes.
    • A OGTT blood glucose level of 200 mg/dL or higher indicates diabetes.
