Reference range: 0–8 ng/mL (Source: ABIM)
Standard unit: ng/mL
High values may indicate
High growth hormone levels may indicate acromegaly in adults, gigantism in children, pituitary tumors, or ectopic GH secretion. Diabetes and malnutrition can also cause elevated GH.
Low values may indicate
Low growth hormone levels may indicate growth hormone deficiency, pituitary damage (from tumors, radiation, or surgery), or hypothalamic dysfunction, leading to growth failure in children and reduced bone density and muscle mass in adults.
Frequently asked questions
- What is a normal Growth Hormone (GH) level?
- A typical reference range for Growth Hormone (GH) is 0–8 ng/mL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Growth Hormone (GH) measured in?
- Growth Hormone (GH) is most commonly reported in ng/mL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Growth Hormone (GH) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Growth Hormone (GH) over time?
- Yes. Upload results from any lab and BloodId charts your Growth Hormone (GH) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
