Normal & Target Blood Glucose Ranges (mg/dL)
For Adult Persons with Diabetes

Before Meals                                                 90-130
1- 2 hours after the start of a meal          less than 180
Hypoglycemia (low) at any time                 70 or below

Normal & Target Blood Glucose Ranges (mg/dL)
For Non-Diabetic Persons

Upon Waking (fasting)                                  70 - 110
    (125 or higher may indicate diabetes)
After Meals                                                  70-140

Important Note:  Your doctor may provide you with different target ranges so be sure to know he/she recommends for your blood glucose levels.

Glucose levels are measured in either:
-  Milligrams per deciliter (mg/dL), in the United States
-  Millimoles per liter (mmol/L) (for those using metric system)

  • Comparatively:
     -  72 mg/dL = 4 mmol/L
    -   90 mg/dL = 5 mmol/L
    -  108 mg/dL = 6 mmol/L
    -  126 mg/dL = 7 mmol/L

    Glucose levels vary before and after meals, at various times of day, as well as throughout the night in persons with diabetes as well as in non-diabetics.  

    ALERT:  Untreated highs and any high over 240 mg/dL can lead to diabetic ketoacidiosis (DKA) which can result in coma and/or death. Test urine for ketones and call your doctor for instructions anytime ketones are in the moderate or higher range no matter what your blood glucose level is.
