Insulin-like Growth Factor-1 (IGF-1) With Z Score

This test measures the level of insulin-like growth factor-1 (IGF-1), a hormone that manages how your body grows and develops. Because IGF-1 levels remain steady throughout the day, this test helps show whether your body is producing a normal amount of growth hormone compared to others your age. It is useful for evaluating causes of slow growth in children or signs of excessive growth in adults. However, an abnormal result indicates a potential hormone imbalance but does not identify the specific medical cause on its own.
