Assessment of diabetic control: a comparison between home and clinic blood glucose levels.

A comparison between blood glucose levels in patients attending a diabetes clinic and in the same patients leading their normal lives showed that for maturity-onset diabetic patients on oral hypoglycemic therapy, the clinic levels were a poor guide to the patients' usual blood glucose. For insulin-treated patients and for those treated with diet alone, the clinic levels were not significantly different from those taken at home or work.
