Part Description

LP14695-8   Somatotropin
Somatotropin (growth hormone) is essential for normal growth and development in children and helps regulate metabolism in both children and adults. The pituitary gland produces and releases GH into the blood in pulses throughout the day.

Because growth hormone is released in pulses, a single measurement of the blood level is not normally clinically useful. Therefore, testing for the suppression or stimulation of growth hormone release from the pituitary is usually done.

GH stimulation (challenge) tests help to diagnose GH deficiency and hypopituitarism. For a stimulation test, a sample of blood is drawn after 10-12 hours of fasting. Then, under close medical supervision, a person is given an intravenous solution of a substance that normally stimulates the release of GH from the pituitary. Blood samples are then drawn at timed intervals and GH levels are tested in each to see if the pituitary gland was stimulated to produce the expected levels of GH. The most commonly used challenge is arginine, but others include clonidine and glucagon. Since exercise normally causes an increase in GH, vigorous exercise may also be used as the stimulant for GH release.

GH suppression tests help to diagnose GH excess. For a suppression test, a sample of blood is drawn after 10-12 hours of fasting. A person is then given a standard glucose solution (usually 100 grams of glucose) to drink. Blood samples are drawn at timed intervals and tested for GH to see if the pituitary gland is sufficiently suppressed by the dose of glucose. Copyright Copyright © 2021 Lab Tests Online.
