What is a normal blood glucose?
The American Diabetes Association and the U.S. Department of Health and Human Services have established levels of glucose that are considered normal and levels that establish a diagnosis of diabetes. These levels refer to the amount of glucose in the blood and are given in units called milligrams per deciliter (mg/dl). Most of the rest of the world uses International Units called millimoles per liter (mmol/L). You can transfer milligrams per deciliter into millimoles per liter by dividing the mg/dl by 18. For example, 126 mg/dl is equal to 7 mmol/L.
