IGF-1 Profile - Serum

The Insulin-Like Growth Factor Type 1 (IGF-1) test measures serum levels of IGF-1 (also called Somatomedin C), an anabolic hormone produced in the liver and essential for maintenance of muscle tissue. Serum levels of IGF-1 vary depending on age, sex, growth hormone secretion, liver function, and nutritional status. Levels below normal are associated with chronic stress and fibromyalgia.
