This test is performed to detect diseases of the pancreas. Trypsin and trypsinogen levels decrease with some types of pancreatic disease and increase with others. Trypsinogen is a precursor of trypsin, an enzyme produced in the pancreas.
Trypsin breaks down protein in the duodenum .
A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the tourniquet is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding . Cotton or a bandage may be applied to the puncture site if there is any continued bleeding. The blood is then analyzed in a laboratory.
