Growth Hormone (Fasting)
The Growth Hormone (GH) blood test measures the level of growth hormone in the blood. Growth hormone is produced by the pituitary gland and plays a vital role in growth, metabolism, muscle mass, bone strength, and overall body composition throughout life. Although growth hormone is most active during childhood and adolescence, it remains important for health and wellbeing in adults.
Because growth hormone is released in pulses throughout the day, measuring it accurately can be challenging. A fasting sample helps reduce variability and improves the usefulness of the result when assessing pituitary function or investigating suspected hormone imbalance.

What is growth hormone and why is it important?
Growth hormone stimulates growth and cell regeneration and helps regulate metabolism. In children, it is essential for normal growth and development. In adults, growth hormone supports muscle strength, bone density, fat distribution, and energy levels.
Too much or too little growth hormone can affect health at any age. Abnormal levels may be linked to pituitary gland disorders or other hormonal imbalances, making accurate testing an important part of endocrine assessment.
Why might I need a growth hormone test?
This test may be recommended if there is concern about abnormal growth patterns in children or symptoms of growth hormone deficiency or excess in adults. Symptoms may include fatigue, reduced muscle mass, increased body fat, reduced exercise capacity, or changes in bone density.
In some cases, growth hormone testing is used as part of the investigation into pituitary gland function, particularly when other hormone levels are abnormal or when imaging studies suggest pituitary involvement.
What do the results mean?
Low growth hormone levels may suggest reduced pituitary function, while elevated levels can be associated with conditions such as acromegaly or other pituitary disorders. Because GH is released in pulses, a single measurement is interpreted carefully.
Results are often considered alongside other hormone tests or dynamic stimulation or suppression tests. Your healthcare professional will explain what your result means and whether further assessment is needed.
How is the test performed?
The test is performed using a blood sample collected during a short appointment. The procedure is routine and our clinical team will ensure you are comfortable throughout.
Do I need to prepare the test?
Fasting is required for this test unless you have been advised otherwise. You should avoid eating or drinking anything except water for the recommended fasting period before your appointment.
