Repeatability of C-peptide response in glucagon stimulation test.
Measurement of the plasma C-peptide level before and after iv administration of 1 mg of glucagon was repeated four times in 10 elderly non-diabetic subjects and in 20 elderly non-insulin-dependent diabetics treated with diet or oral drugs to assess the repeatability of the C-peptide responses. Plasma C-peptide levels before and after glucagon administration and C-peptide glucose ratios in the four measurements did not differ significantly from test to test either in diabetic or non-diabetic subjects. The results of the present study indicate that the repeatability of C-peptide response to glucagon is very good both in non-insulin-dependent diabetics and in non-diabetic subjects.
