Tests
Growth hormone (GH) tests are blood tests that check if your body is making a normal amount of GH. Hormones are chemical messengers in your bloodstream that control the actions of certain cells or organs. GH, also known as human growth hormone, controls your body's growth. It also helps control metabolism, the process your body uses to make energy from the food you eat. GH is made in the pituitary gland , a small organ at the base of your brain that controls many functions, including growth.
