Why is the Test Performed?

This test is used to confirm the presence of a VIPoma, a tumor that secretes VIP.

VIP is found throughout the body, but in highest concentration in the nervous system and gut. VIP has many functions:

it may be a neurotransmitter or neuromodulator
it increases water and electrolyte secretion from the pancreas and gut
it stimulates the release of hormones from the pancreas, gut, and hypothalamus
it stimulates breakdown of fat and glycogen
it stimulates bile flow
it inhibits gastrin and gastric acid secretion
