Called hypoglycemia, this deficiency of glucose in the blood is considered critical at, or below, 40 milligrams of glucose per deciliter of blood, or 40 mg/dL. However, this figure must be adjusted individually, as the exact level at which an a person develops symptoms varies.
A normal (non-diabetic) level is between 70 mg/dL and 100 mg/dL. The test is administered in the morning prior to eating, as the test requires a âfastâ of at least 8 hours, otherwise the results will be skewed. A blood glucose level above 126mg/dL is considered a diabetes diagnosis (subject to a confirmatory test).n fact, managing your blood sugar levels (also known as glucose levels) is the core focus of your diabetes self management plan. It doesnât matter if you are focused on your diet, exercise, insulin or medications, all of these components are geared towards managing your sugar levels.
