[Our experience with the radioimmunoassay of insulin: Its practical value. Apropos of 140 cases]

What is the interest of insulin determinations in diabetics? The interest is considerable, scientifically, particularly in obese patients with hyperinsulinism. In practice, in intermediate cases of diabetes, it may help in deciding whether or not to administer insulin. The authors studied insulin secretion in various varieties of diabetes and its role in the onset of vascular complications. Low insulin secretion seems to favour the development and frequency of the latter.
