Trypsin-secretin test

Pancreatic exocrine function is divided into direct test and indirect test. The direct test is to collect pancreatic juice directly after intubation to the duodenum, or directly stimulate pancreas secretion with certain gastrointestinal hormones to understand its exocrine state. Its sensitivity and specificity are relatively good, but because the intubation causes some pain to the patient, it is not easy to be applied in clinical practice. There are many methods for indirect tests. It is not necessary to intubate and measure pancreatin degradation products, or to detect pancreatin degradation products with a nuclide to indirectly understand pancreatic exocrine function status.
