Human Growth Hormone
Human growth hormone (hGH) is a hormone that is naturally produced by the body. It is synthesized and secreted by cells in the anterior pituitary gland located at the base of the brain. hGH stimulates many metabolic processes in cells. hGH affects protein, fat, carbohydrate and mineral metabolism. Its secretion into the circulation follows a pulsatile pattern resulting in widely fluctuating blood levels that are influenced by multiple factors such as age, gender, sleep, physical activity, diet, stress, fever, steroids and the environment. Measurement of GH is primarily of interest in the diagnosis and treatment of various forms of inappropriate growth hormone secretion.
This hGH blood test can help identify a growth hormone deficiency or excess. hGH testing is critical to assess the levels of hGH in children, especially those children who exhibit problems with growth or show abnormal growth patterns. Testing helps identify any form of deficiency of the hormone. These tests are done on children before they reach adolescent age, in order to provide a window of opportunity to rectify the imbalance in time.
It typically takes 4 business days or less.
An 8-12 hour fast is recommended before testing.
