"normal" is considered to be 100mg/dl or less. There is a little leeway before a level is high enough to raise concern and necessitate intervention though. A non-fasting blood sugar - or random should be less than 150... Especially 2 hours after you eat. ...Read more

Normal fasting: 65-105 when drawn out of a vein while fasting. Various authorities have different "normal" levels. There are, however, no exact cut-offs, it's all a continuium.

An a1c >6% is also suggestive and needs further evaluation. See diabetes.Org for info. ...Read more

If my blood glucose levels were 5.9 after doing my fasting in the morning, does that mean I am borderline diabetic?

If my blood glucose levels  were 5.9 after doing my  fasting  in the morning,  does that mean I am borderline diabetic?

Nope: I assume you're talking about the a1c reading. Non-diabetic readings are between 4.0-6.0, so you should be good. The a1c is an index number that averages out the previous 100 days of blood sugars into 1 number that gives you an idea of what glucose levels have been. This is pretty much diagnostic that you are not diabetic. Continue a prudent, low-carb diet & active lifestyle to maintain that, tho! ...Read more
