Normal Values

A normal peak value is at least 10 ng/mL; 5-10 ng/mL is indeterminate; 5 ng/mL is subnormal. (A normal value rules out hGH deficiency; in some laboratories, the normal level is 7 ng/mL.)

Note: ng/mL = nanogram per milliliter.


What abnormal results mean

Failure of this test to raise hGH levels indicates there is a diminished amount of hGH stored in the anterior pituitary. In children, this results in dwarfism. In adults, it may be associated with panhypopituitarism or adult growth hormone deficiency.
