Growth hormone(GH) tests are blood tests that check to see if your body is making a normal

amount of GH. GH, also known as human growth hormone, is a substance that controls your

body's growth. It also helps control metabolism, the process of how your body uses food and

energy. GH is made in the pituitary gland, a small organ in the base of the brain.

In children, GH plays a major role in bone growth, development of muscle mass, and height.

In adults, GH affects bone and muscle health. If children or adults have too much or too

little GH, it can cause health problems.
