Indicator Explainer
Somatotropin
Somatotropin (217 aa, ~25 kDa) is encoded by the human GH1 gene. This protein is involved in the regulation of many physiologic processes, including the growth of organs and tissues and the metabolism of amino acids and proteins.
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.
