| Usage: |
As human growth hormone (HGH) levels in normal & diseased populations overlap, and HGH stimulation test is needed to evaluate hGH deficiency in cases of growth retardation, short stature, and dwarfism. To diagnose hGH deficiency as a cause of retardation, at least two different stimulants should be used on different days for confirmation. Exercise to be used as an initial stimulant followed by any other provocative agent. Stimulation of hGH value to >8 ng/mL is considered normal. Lack of stimulation indicates hGH deficiency. |
