Description: The Insulin-like Growth Factor 1 (IGF-1 test) testing may be used to monitor growth hormone therapy, evaluate pituitary function or identify growth hormone deficiencies or overproduction. IGF-1 is a hormone produced by the liver, muscle and other tissues in response to Growth Hormone (GH) production from the pituitary gland and is vital for normal tissue and bone growth and development. The level of IGF-1 is stable througout the day, making it a good indicator of GH level averages. Turnaround time for the IGF-1 test is typically 1-3 business days.
Requirements: IGF-1 testing does not have any special requirements.
