The 4 tests in this panel
What each one measures and the range labs usually print for adults. Ranges differ a little between labs, so the range on your own report is the one your result is judged against.
Growth Hormone (GH)
A hormone from the pituitary gland that drives growth in children and helps manage body composition in adults. It is released in bursts, so one level is hard to interpret.
- Men, 18+
- 0.02–0.97 ng/mL
- Women, 18+
- 0.02–3.61 ng/mL
IGF-1 (Insulin-like Growth Factor 1)
A protein your liver makes in response to growth hormone. It's a steady signal of growth hormone activity, and usual levels vary a lot with age and sex.
- Men, 18
- 145–506 ng/mL
- Women, 18
- 117–430 ng/mL
- Men, 19
- 122–435 ng/mL
- Women, 19
- 113–408 ng/mL
IGF-1 Z-Score (SDS)
A score that shows how far your IGF-1 result is from the average for people of your age and sex, in standard deviations. Labs usually print it next to IGF-1.
- Adults
- -2–2 SD
IGFBP-3 (IGF Binding Protein 3)
A protein made mostly in the liver that carries IGF-1 in the blood. It rises and falls with growth hormone and with nutrition, and usual levels change a lot with age.
- Men, 18
- 2,678–6,327 µg/L
- Women, 18
- 2,749–6,510 µg/L
- Men, 19
- 2,700–6,341 µg/L
- Women, 19
- 2,779–6,527 µg/L
