Insulin-like Growth Factor 1 (IGF-1) Analysis
Insulin-like Growth Factor 1 (IGF-1) Analysis is a blood test that measures the level of IGF-1 in the blood. IGF-1 is a hormone similar in molecular structure to insulin and plays an important role in childhood growth and continues to have anabolic effects in adults. It is primarily produced in the liver and its production is stimulated by growth hormone (GH) released from the pituitary gland. This test is often used to evaluate growth hormone activity and can be helpful in diagnosing growth hormone deficiencies or excesses.
Reference Range:
Normal Range: Vary based on age, sex, and pubertal stage.
Management of high IGF-1 levels includes using medications to suppress growth hormone production, surgical removal of pituitary tumors, or radiation therapy, while low levels may be treated with growth hormone therapy to promote growth in children and improve adult body composition. Regular monitoring of IGF-1 levels is vital for patients undergoing treatment for growth hormone imbalances to fine-tune dosages and evaluate the effectiveness of the treatment. IGF-1 Analysis is critical in diagnosing growth hormone imbalances, guiding management of conditions such as acromegaly, gigantism, and growth hormone deficiency, ensuring tailored treatment adjustments based on ongoing assessment of IGF-1 levels.
