Test Information
Vasoactive intestinal polypeptide (VIP) was originally isolated from porcine small intestine and was recognized by its potent vasodilator activity. This brain/gut hormone has widespread distribution and is present in neuronal cell bodies localized in the central nervous system, digestive, respiratory, and urogenital tracts, exocrine glands, and thyroid and adrenal glands. VIP has a wide scope of biological actions. The main effects of VIP include relaxation of smooth muscle (bronchial and vascular dilation), stimulation of gastrointestinal water and electrolyte secretion, and release of pancreatic hormones.
 
VIP producing tumors (VIPomas) are rare; most (90%) are located in the pancreas. Watery diarrhea, hypokalemia, and achlorhydria are key symptoms
Reference Range Information
Performing Location Reference Range
​Mayo Medical Laboratories ​<75 pg/mL
Interpretation
Values >75 pg/mL may indicate presence of enteropancreatic tumor causing hypersecretion of vasoactive intestinal polypeptide (VIP).
 
Values >200 pg/mL are strongly suggestive of VIP producing tumors (VIPoma).
 
VIPoma is unlikely with a 24-hour stool volume <700 mL.
