A growth hormone (GH) level test measures the amount of growth hormone in your blood. It is ordered to evaluate symptoms of GH excess or deficiency, such as abnormal growth, unexplained weight changes, or fatigue. Because GH is released in pulses, results are often interpreted with other tests.

What it measures

  • Growth hormone — The main hormone measured; levels fluctuate throughout the day.
  • IGF-1 — A hormone made in response to GH; often checked alongside GH for a clearer picture.
  • Glucose — Blood sugar may be measured during a suppression test to see if GH drops as expected.
  • Other pituitary hormones — Sometimes checked to see if other hormone-producing glands are affected.

Who it is for

A doctor may order this test if you have symptoms of too much or too little growth hormone, such as unusual growth, vision changes, or persistent fatigue. It is also used to monitor known pituitary conditions.

Preparation

Preparation depends on the specific test: some require fasting for 8–12 hours, while others need you to avoid strenuous exercise or certain medications beforehand. If no special preparation is needed, your doctor will tell you.

Results and what they mean

Results are usually reported as a number with a reference range, but normal ranges vary by age, sex, and testing method. A clinician interprets your results along with your symptoms and other tests. This is general information, not medical advice; discuss your results with a healthcare professional.

Frequently asked questions

Do I need to fast for this test?

It depends on the specific protocol. Some GH tests require fasting, while others do not. Follow your doctor's instructions.

Why does my GH level fluctuate?

Growth hormone is released in bursts, especially during sleep, so a single random level can be hard to interpret. Your doctor may order a stimulation or suppression test for clarity.

How long until I get results?

Typical turnaround is 1–3 business days, but it may be longer if special handling or additional tests are needed.

Can I take my medications before the test?

Some medications can affect GH levels. Ask your doctor whether to take them as usual or skip them before the test.
