Main Uses
Growth Hormone testing is primarily used to diagnose growth disorders in children, evaluate pituitary function, and monitor treatment effectiveness in patients with growth hormone deficiencies or excesses. It is also used to diagnose acromegaly and gigantism, and to assess the function of the pituitary gland in cases of suspected pituitary tumors or other endocrine disorders.
Normal Range
The normal range for Growth Hormone (GH) varies depending on the assay and the time of day, as GH is secreted in a pulsatile manner. Typically, for adults, the normal range is between 0.4 to 10 ng/mL. However, this can vary, and it's important to refer to the specific lab's reference range.
Low Values - Possible Causes
Possible causes of low values include: Hypopituitarism, Sheehan's syndrome, Pituitary tumors or damage, Radiation therapy to the brain, and Genetic conditions such as Prader-Willi syndrome.
High Values - Possible Causes
Possible causes of high values include: Acromegaly, Gigantism, Tumors of the pituitary gland, Excessive use of growth hormone supplements, and Rare genetic syndromes like McCune-Albright syndrome.
