The Growth Hormone, Serum test is used to measure the level of growth hormone (GH) in the blood. This hormone is essential for regulating growth and development and plays an important role in metabolism. The test is used to diagnose various disorders, including short stature in children, abnormal excessive growth, and conditions related to the pituitary gland. The blood sample is collected at specific times because growth hormone levels fluctuate throughout the day. The results of this test help doctors determine appropriate treatment plans and gain a better understanding of the patient’s health status.
