What is the Growth Hormone (GH) Test?
The Growth Hormone (GH) test measures the level of growth hormone in the blood. GH is produced by the pituitary gland in the brain and plays a key role in childhood growth, muscle maintenance, and metabolism in adults. Because GH is released in pulses throughout the day, a single measurement is often combined with stimulation or suppression tests for a more accurate result.
Why is the Growth Hormone Test Done?
- To investigate short stature or slow growth in children
- To diagnose Growth Hormone Deficiency (GHD) in both children and adults
- To detect excess GH production — which can cause gigantism in children or acromegaly (abnormal bone growth) in adults
- To monitor children receiving growth hormone therapy
- To evaluate pituitary gland function as part of a hormone panel
Normal Growth Hormone Levels
| Group | Normal Fasting GH Level |
|---|---|
| Adult men | 0.4 – 10 ng/mL |
| Adult women | 1 – 14 ng/mL |
| Children | Higher and more variable (stimulation test preferred) |
Because GH fluctuates significantly throughout the day, a single low result does not confirm deficiency. Doctors usually use a GH stimulation test (with insulin or arginine) for a definitive diagnosis. A persistently high GH level may point to a pituitary tumour.
How to Prepare for the Growth Hormone Test
- Fast for at least 8 hours before the test — eating raises insulin and suppresses GH
- Avoid heavy exercise and emotional stress before the test, as both can temporarily raise GH levels
- Blood is usually collected in the morning for the most consistent baseline reading
- Inform your doctor about any steroids, hormones, or other medications you take
- If a stimulation or suppression test is ordered, follow the specific preparation instructions given by your doctor
