  • Glucose

    Glucose is the sugar in your blood and your body's main fuel. This test shows how much is there at the moment the sample is drawn.

    Adults
    70–99 mg/dL

  • Glucose, OGTT 1-Hour

    Blood glucose one hour after a measured sugar drink in an oral glucose tolerance test. In pregnancy, a high 1-hour value is one criterion for gestational diabetes.

  • Glucose, OGTT 2-Hour

    Blood glucose two hours after a 75 g sugar drink. It is the main OGTT value used to sort glucose tolerance into normal, prediabetes and diabetes ranges.

    Adults
    up to 139 mg/dL

  • Glucose, OGTT 3-Hour

    Blood glucose three hours after a 100 g sugar drink. It is the last value of the 3-hour glucose tolerance test used in pregnancy.
