Arterial calcium stimulation with hepatic venous sampling (ASVS) is an invasive diagnostic study which is used when all other imaging studies are inconclusive. ASVS is also the diagnostic test of choice for endogenous hyperinsulinism. Findings are noted after calcium stimulation of tumor supplying arteries and in the hepatic venous samples which show the positive response of a two-fold or greater increase in insulin levels.
