What is a Vasoactive Intestinal Peptide Test?

Vasoactive intestinal peptide (VIP) testing is a process used to measure levels of VIP in the bloodstream. VIP is a hormone that is produced by the pituitary gland and helps to regulate several important bodily processes. VIP levels in the blood can be used to diagnose several conditions, including digestive issues, hormonal imbalances, adrenal problems, and tumors.

Preparation for a Vasoactive Intestinal Peptide Test

No preparation is required for a VIP test. The healthcare provider will give instructions on how to collect the sample. Usually, the sample is taken with a needle and small tube and only a few drops of blood are needed.

Procedure for the Vasoactive Intestinal Peptide Test

The procedure for a VIP test is simple. A healthcare provider or technician will draw a sample of blood from a vein in the arm. The sample will then be sent to a laboratory for testing. Results of the VIP test are usually available within three to five days.

Types of Vasoactive Intestinal Peptide Testing

VIP testing can be done in either a single-test or a double-test format. The single-test format measures the level of VIP in the blood. The double-test format also measures the level of VIP in the urine.

Risks of the Vasoactive Intestinal Peptide Test

The risk of infection or bleeding from a VIP test is very low. The puncture site may become sore or bruise, but this should go away in a few days.

Why the Vasoactive Intestinal Peptide Test is Done

The VIP test can be used to diagnose several conditions, such as digestive issues, hormone imbalances, adrenal problems, and tumors. It can also be used to monitor treatment progress and gauge the body’s response to medications.

When a Vasoactive Intestinal Peptide Test is Done

A VIP test may be done as part of a routine exam or as part of a larger workup for a specific issue. The healthcare provider will determine when and why the test is necessary.
