Clinical significance: |
Measurement of GH is primarily of interest in the diagnosis and treatment of various forms of inappropriate growth hormone secretion. Growth hormone measurements in children are used in the evaluation of short stature and help differentiate low GH production from other sources of growth failure. Stimulation and suppression tests are often more meaningful than random measurements. |
