The IGF-1 (Insulin-like Growth Factor 1) test measures the level of this important hormone, which is primarily produced in the liver in response to growth hormone (GH) stimulation. IGF-1 plays a vital role in growth and development, influencing muscle growth, fat metabolism, and overall energy levels. Abnormal IGF-1 levels can indicate growth hormone deficiencies or excesses, which can lead to various health issues. This test is essential for those looking to assess their growth hormone function, particularly individuals with growth disorders or symptoms related to hormonal imbalances.
