I've been type I for 37 years. I've always been good at keeping my BS under control. Last A1c test was 4.7. My endocrinologist lowered my insulin. I know they want it below 6.0. Last time I saw him it was 5.0 and he said that's what his would be being non-diabetic. I'm going to get off here and do a search for A1c test results to see if I can find out what a non-diabetic would be. Good luck and good health to all.

For people who aren't taking insulin, under 5% is not a problem. Because you are on insulin he doesnt want you to be that low since your A1C is an average of fastings and post-prandials and keeping you too low all the time could result in a hypoglycemic unawareness that could result in all kinds of bad things...including death if you were too low. The non-diabetic body produces glucagon in response to low blood sugar naturally produced by the body. The body produces insulin at such a small rate that the same glucagon response is not able to defeat an injection of insulin and to get the response that is needed for a low that comes from an injection your body just cant keep up.

Jerrytom,
Most sites that give target ranges for A1c for diabetics, such as the Joslin Diabetes Center and the American Diabetes Association, consider 6.5 and below to be excellent control.

If you can keep your A1c's to 5.0 without also experiencing a lot of hypoglycemic episodes, then you are doing fantastic!

You should find that non-diabetic will be 4.5 to 4.7. That range can be higher, but the 'norm' will be mid 4's.

You are in excellant control. I believe doctors want people to control in a higher range because of how difficult it is to maintain such excellant control. It is just safer to have that buffer because of the dangers of gong too low. There are a lot of people that are able to maintain that kind of control with great control and knowledge what it takes to get and staty there.
