Insulin-like growth factor 1 (IGF-1, or somatomedin C), a protein involved in stimulating somatic growth, is regulated principally by growth hormone (GH) and nutritional intake. IGF-1 is transported in serum by several proteins; this helps maintain relatively high IGF-1 plasma levels and minimizes fluctuations in serum IGF-1 concentrations. Measuring IGF-1 is useful in several growth-related disorders. Dwarfism caused by deficiency of growth hormone (hypopituitarism) results in decreased serum levels of IGF-1, while acromegaly (growth hormone excess) results in elevated levels of IGF-1. IGF-1 measurements are also helpful in assessing nutritional status; levels are reduced in undernutrition and restored with a proper diet.

Collect blood in a red-top or SST vacutainer. For red-top
vacutainers, allow blood to clot (10-15 minutes) at room temperature.
Separate serum from cells and refrigerate. If sample collected in
glass collection tube, transfer to plastic container.
