Growth Hormone Blood Test

About this test

Growth hormone (hGH), or somatotropin, is a hormone responsible for normal body growth and development. It works by stimulating protein production in muscle cells and energy release from the breakdown of fats.

Growth hormone is made by the pituitary gland and is needed for growth. The amount of growth hormone in the blood changes during the day and is affected by exercise, sleep, emotional stress, and diet. It plays an important role in how the body uses food for energy (metabolism).

Who is this test for?

This test can be used to identify problems with the production of human growth hormone. This may involve multiple tests throughout the day and is usually taken under the care of an endocrinologist, as medication to stimulate growth hormone release may be needed for the test. Levels of growth hormone vary widely throughout the day so a single measurement of growth hormone is of limited use.

Insulin-like growth factor 1 (also known as somatomedin C) can be used to screen for growth hormone problems, and is better suited to being used as a single test because its levels vary less throughout the day.
