Vasoactive intestinal polypeptide (VIP) is a substance found throughout the body. The highest levels are normally found in the nervous system and gut. VIP has many functions:
A blood test can be done to find out how much VIP you have in your blood.
A blood sample is needed. For information on how this is done, see: Venipuncture.
You should not eat or drink anything for 4 hours before the test.
When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
This test is used to confirm the presence of a VIPoma, a tumor that releases VIP.
