Clinical Significance:
Measurement of GH is primarily used for the diagnosis and treatment of disorders of growth hormone secretion, including GH excess (acromegaly) and deficiency. Growth hormone measurements in children are used in the evaluation of short stature and help differentiate short stature, due to low GH production from other causes of growth failure. Stimulation and suppressoin tests are often more meaningful than random measurements.
