What AIGR value suggests insulinoma?

AIGR >50 µU/mg during symptomatic hypoglycemia is suggestive of inappropriate insulin secretion consistent with insulinoma. Values should be interpreted alongside C-peptide and proinsulin levels.

What other tests confirm insulinoma alongside AIGR?

Confirmatory tests include: C-peptide >200 pmol/L, proinsulin >5 pmol/L, beta-hydroxybutyrate <2.7 mmol/L, and insulin ≧3 mIU/L during documented hypoglycemia (<55 mg/dL) with Whipple's triad present.

Insulinoma AIGR — Amended Insulin-to-Glucose Ratio

Calculate the Amended Insulin-to-Glucose Ratio (AIGR = insulin IU/mL × 100 / (glucose mg/dL − 30)) during a 72-hour fast to assess inappropriate insulin secretion in suspected insulinoma.
