IGF-1 (Somatomedin C)

IGF-1, also called somatomedin C, is structurally similar to insulin and plays an important role in bone and tissue growth. This hormone is produced primarily in the liver in response to growth hormone (GH) stimulation. Unlike GH, which fluctuates throughout the day, IGF-1 levels remain stable, making it a reliable marker for evaluating the overall GH activity.

The IGF-1 (Somatomedin C) test is advised when a child has growth and development abnormalities such as short stature or slow/delayed growth. Also, it is to be considered when an adult has reduced bone density and muscle mass and increased levels of lipids, it may be linked to insufficient GH and IGF-1 production. Moreover, the IGF-1 (Somatomedin C) test is recommended when there are signs and symptoms of gigantism in children or acromegaly in adults; when there is a suspicion of a pituitary disorder; or during and after treatment for GH disorders. Furthermore, the IGF-1 (Somatomedin C) test is suggested along with other hormone tests for a comprehensive assessment.

Overnight fasting of 8-12 hours is required before the test. However, drinking water is permissible. Inform a doctor about any medications or supplements taken, as some (like estrogen or high-dose steroids) can affect IGF-1 levels.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Do not self-medicate, and always consult a doctor to understand the test results correctly. These results help determine whether growth, hormone levels, and metabolism are functioning normally.
