Secretin stimulation test. The secretin stimulation test measures the ability of the pancreas to respond to a hormone called secretin. The small intestine produces secretin when partially digested food from the stomach moves into the area. The doctor inserts a tube through your nose and into your stomach.

The fluids released from the pancreas into the duodenum are removed through the tube over the next 1 to 2 hours.
