Reference Range
Random growth hormone (GH) levels in a healthy person range as follows:
Men: < 5 ng/mL or < 226 pmol/L
Women: < 10 ng/mL or < 452 pmol/L
Children: 0-20 ng/mL or 0-904 pmol/L
Newborns: 5-40 ng/mL or 226-1808 pmol/L
GH suppression test value (using 100 g glucose) in a healthy person is as follows:
< 0-2 ng/mL or 0-90 pmol/L or undetectable
GH stimulation test values (using arginine, glucagon, or insulin) are as follows:
Normal peak value: >10 ng/mL or >452 pmol/L
Intermediate peak value: >5 ng/mL or >226 pmol/L
Subnormal peak value: < 5 ng/mL
SI Units = Conventional Units X 1 (mcg/L = ng/mL X 1)
