Secretin Stimulation Test (SST)

What is a Secretin Stimulation Test? Image

This test measures the ability of the pancreas to respond to a hormone called secretin. The small intestine produces Secretin when partially digested food has moved into the intestine from the stomach. Your doctor has requested this test, which will indicate the response of Gastrin, a naturally occurring hormone, to the injection of a medication called Secretin. During the test, a small tube (a catheter) will be placed in your arm to take blood samples and infuse the medication Secretin. The stimulation test lasts approximately two hours and is performed in the GI Physiology Laboratory in the Medical Procedures Unit.
