Concerned about growth in children, experiencing unexplained fatigue and metabolic issues as an adult, or want to evaluate pituitary function and hormone balance?
The Growth Hormone (GH) Blood Test measures a hormone that controls growth, muscle mass, and how your body uses fat and sugar. Abnormal levels can affect height in children, muscle strength, energy, and metabolism in adults.

The Growth Hormone (GH) Blood Test measures a hormone that controls growth, muscle mass, and how your body uses fat and sugar. Abnormal levels can affect height in children, muscle strength, energy, and metabolism in adults.
Think of growth hormone as your body's master builder and renovator – it's the hormone responsible for helping children grow tall and keeping adults' muscles strong, bones dense, and metabolism humming. Produced by your pituitary gland (a small but mighty gland at the base of your brain), this hormone works around the clock, with levels naturally peaking while you sleep to repair tissues and maintain your body's essential functions.
A Growth Hormone test measures whether your body is producing the right amount of this vital hormone, which can reveal important insights about your health. In children, low levels might explain slow growth or delayed development, while in adults, deficiency can lead to stubborn belly fat, muscle weakness, bone thinning, and persistent fatigue. On the flip side, too much growth hormone can cause features like hands and feet to enlarge unnaturally. Whether you're concerned about your child's growth patterns or experiencing unexplained changes in your energy, body composition, or recovery from exercise, this test helps pinpoint whether your body's internal renovation crew is working properly.
You may benefit from the Growth Hormone (GH) Blood Test
Essential for individuals with growth disorders, suspected GH deficiency, pituitary dysfunction, or anyone needing growth hormone and metabolic assessment.
Feeling tired all the time
Loss of muscle mass or sarcopenia
Age-related muscle loss
Anti-aging health assessment
Difficulty growing facial hair (men)
How to prepare
Timing is crucial as GH levels fluctuate. May require fasting or stimulation testing. Avoid exercise before testing. Inform healthcare provider of all medications, particularly those affecting GH levels.
Understanding results
Results show GH levels compared to normal ranges for age and testing conditions. Abnormal levels may indicate growth disorders, pituitary dysfunction, or other endocrine conditions requiring specialist evaluation.
After the test
Address abnormal GH levels through comprehensive endocrine evaluation, appropriate hormone replacement therapy if deficient, treatment of underlying pituitary disorders, and regular monitoring. Work with endocrinologists.
Frequently Asked Questions
In children: short stature, delayed growth, delayed puberty. In adults: fatigue, increased body fat, decreased muscle mass, reduced bone density, poor exercise capacity.
Treatment involves daily growth hormone injections, with doses adjusted based on response, age, and individual needs, typically showing improvements within months.
IGF-1 is produced in response to GH and mediates many of GH's effects. IGF-1 testing is often used alongside GH testing as it's more stable and reflects average GH activity.
Yes, adults with confirmed GH deficiency can benefit from therapy with improvements in body composition, energy levels, exercise capacity, and quality of life.
Causes include pituitary tumors, head trauma, genetic conditions, radiation therapy, infections, or sometimes the cause is unknown (idiopathic).
When properly monitored, GH therapy is generally safe, but potential side effects include joint pain, fluid retention, and rarely, increased cancer risk, requiring regular monitoring.

Having seen the GP regularly, I thought I had everything covered. I had no idea I had Type II diabetes as I was symptomless. Now I can manage it before it gets really bad. I never would have caught it this early if I hadn't used Bloody Good.
