Blood Glucose Blood glucose is the main sugar found in the blood and the body's main source of energy. It is getting into the higher range of normal, but it is in the non-BG dysregulated range.

While it might sound like the ideal A1C target is under 6.0, for those with diabetes, this level can indicate low blood sugar levels, which can be just as dangerous as high blood sugar levels.
