    Blood Sugar Tests

    Fasting Blood Sugar (FBS):

    This test measures blood sugar levels. High levels indicate diabetes and insulin resistance, in which the body cannot handle sugar properly.

    Target Values:

    . Less than 100 mg/dl = normal

    . Between 110 – 125 mg/dl = impaired fasting glucose (prediabetes)

    . Greater that 126 mg/dl on two or more samples = diabetes

    Preparation:

    The test requires a 12 hours fast. You should wait to eat or take insulin or oral hypoglycemic until the test has been drawn, unless told otherwise.

     

    Glycosylated Hemoglobin or Hemoglobin A1C (HbA1C):

    Determines average blood sugar levels over the preceding 90 days. Elevated levels are associated with prediabetes and diabetes.

    Target Values:

    . 5.7 – 6.4 % indicates increased risk for development of diabetes (prediabetes). Lifestyle modification would be beneficial

    .  6.5 % or more is considered diabetic

    Preparation:

    The test can be measured anytime of the day without fasting.
