Indicator Explainer
Glucagon
Glucagon (29 aa, ~3 kDa) is encoded by the human GCG gene. This protein plays a role in the regulation of blood sugar levels through the stimulation of hepatic glycogenolysis and gluconeogenesis.
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.
