WebDec 1, 1997 · Plasma levels of proinsulin and its conversion intermediates are elevated in NIDDM patients. Recent studies have suggested that proinsulin levels are also increased relative to insulin levels in subjects who subsequently develop NIDDM. This may be due to insulin resistance or a defect in proinsulin processing or insulin secretion.
WebIn patients with insulinoma, C peptide is ≥ 0.6 ng/mL (0.2 nmol/L) and proinsulin is ≥ 5 pmol/L. These levels are normal or low in patients with surreptitious insulin administration.
