WebApr 1, 2003 · Hirshberg et al. ( 19) reported that proinsulin level has a diagnostic sensitivity for insulinoma of 90% at the start of a fast and 82% at the end of a fast. Thus, elevated proinsulin has been a slightly more reliable marker than elevated C-peptide in diagnosing a functional islet cell tumor. WebFeb 22, 2024 · Normal individuals will have proinsulin concentrations below the upper limit of the normal fasting reference range (22 pmol/L) when hypoglycemic (blood glucose <60 mg/dL). Conversely, most (>80%) insulinoma patients will have proinsulin concentrations above the upper limit of the reference range.

WebProinsulin (PI)5 conversion to insulin usually is almost completed before secretion, and proinsulin-like material thus represents only 10–20% of serum immunoreactive insulin in fasting healthy subjects (1, 2). Intact human pro-insulin (hPI) and des (31,32)-hPI, usually in almost equimo-lar amounts (3), are the major circulating forms of insulin 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.
