This is a blood test used to evaluate growth hormone levels. Growth hormone is the hormone which makes you grow. For example, a high level of this hormone may cause a giant to develop. This test is often used with people who are short, have delayed sexual maturity, or have other growth deficiencies. It is also used to find the cause of enlargement in persons who show signs of gigantism, persons with unusually large bone structure, or to help screen for pituitary malfunction.
