IGF-1 Monitoring

Meaning

IGF-1 Monitoring is the clinical practice of measuring circulating levels of Insulin-like Growth Factor 1 (IGF-1) to assess the function of the somatotropic axis and to guide the dosing of growth hormone-related therapies. As IGF-1 is the primary mediator of Growth Hormone (GH) action, its serum concentration provides a stable, integrated biomarker of average GH secretion over time. This monitoring is essential for ensuring therapeutic efficacy and mitigating potential side effects in patients undergoing GH treatment.
