Indicator Explainer
Gastrin
Gastrin (101 aa, ~11 kDa) is encoded by the human GAST gene. This protein plays a role in the modulation of gastric acid and pancreatic digestive enzyme secretion.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
