What is the purpose of this test?
If you suspect that you or someone you know may be experiencing growth hormone deficiency (GHD) or growth hormone excess, it's important to get an accurate diagnosis. One way to do this is by ordering the Growth Hormone Blood Test Panel. This test panel is designed to evaluate pituitary function, monitor the effectiveness of GH treatment, and help diagnose GHD or excess GH. By analyzing the levels of growth hormone and insulin-like growth factor-1 (IGF-1) in the blood, this panel can provide valuable insights into the functioning of the endocrine system, which regulates hormones throughout the body. If you have concerns about growth hormone levels, talk to your healthcare provider about ordering this test panel.
The Growth Hormone Blood Test Panel includes the following:
Human Growth Hormone (HGH)
The human body releases growth hormone (HGH) from the pituitary gland in a pulsatile manner throughout the day. This hormone is essential for the normal growth and development of children, and it regulates various bodily functions in adults, such as bone density, muscle mass, and lipid metabolism. Additionally, it plays a significant role in tissue repair, muscle growth, bone strength, brain function, physical and mental health, energy, and metabolism. Growth hormone testing is primarily used to diagnose growth hormone deficiency and evaluate pituitary gland function, often as a follow-up to other abnormal pituitary hormone test results. The test is also used to detect excess growth hormone and to diagnose and monitor the treatment of acromegaly and gigantism.
Insulin-like Growth Factor Test (IGF-1)
Human growth hormone (HGH) plays a crucial role in promoting human growth and development. In response to the stimulation of HGH, insulin-like growth factor 1 (IGF-1) is produced in the liver and muscles. The IGF-1 Blood Test is an important diagnostic tool for identifying and monitoring patients with HGH-related issues, such as growth hormone deficiency, acromegaly, and gigantism. It is also used to monitor patients who are undergoing HGH therapy to ensure that their treatment is effective and safe.
When should I order a Growth Hormone Blood Test Panel?
Individuals may order this test if they have experienced symptoms related to an HGH deficiency or excess. Common signs and symptoms of HGH deficiency or hypopituitarism include:
- Decreased bone density
- Fatigue
- Adverse lipid changes, such as high cholesterol
- Reduced exercise tolerance
Signs and symptoms of HGH excess include:
- Skin thickening
- Sweating
- Fatigue
- Headaches
- Joint pain
- Enlarged hands and feet
- Enlarged facial bones
- Carpal tunnel syndrome
- Abnormally enlarged internal organs
- Skin tags
- Intestinal polyps
