What Is a Good Blood Reading for Diabetics?

A good blood glucose reading before eating ranges from 70 to 130 milligrams per deciliter, and one or two hours after a meal, a normal reading is less than 180 milligrams per deciliter, as stated by the American Diabetes Association.

Overall, a three-month average for a normal blood glucose level is a hemoglobin A1c of less than 7 percent, according to the American Diabetes Association.

Diabetics check blood glucose levels to ensure insulin levels are properly maintained. People who commonly check their levels include patients who take insulin, pregnant diabetics, those who have difficulty controlling blood glucose levels and diabetics who often have low glucose levels, explains the American Diabetic Association.
