A diabetes chart outlines what the normal blood glucose ranges are for a person who has diabetes and a person who does not, according to the Joslin Diabetes Center. People use it as a model to figure out what their target levels should be and assist in monitoring their blood glucose regularly.
The chart states that before breakfast, when people fast through the night, the goal blood glucose levels should be between 70 and 30 milligrams per deciliter, explains the Joslin Diabetes Center. This level should be the same before lunch, supper and snack as well. Two hours after eating, the target blood glucose levels should be less than 180 milligrams per deciliter. At bedtime, the blood glucose range should be between 90 and 150 milligrams per deciliter, and the general reading for A1C should be less than 7 percent. The chart also lists the target glucose levels for people without diabetes.
Medical professionals recommend that diabetes sufferers track and record their readings in their own charts, reports Healthline. Healthline offers a blank, printable diabetes chart for people to track their own levels. Any glucose level above 180 milligrams per deciliter is too high, while a glucose level below is 50 milligrams per deciliter is alarmingly low.
