Description
Estimated cost for Growth Hormone Test at general public hospitals in China is about ¥140-400, and at Grade 3A hospitals about ¥200-500, varying by hospital tier and region.
Main Uses
Growth hormone testing is primarily used to diagnose growth hormone deficiency or excess. It is applicable in scenarios such as evaluating short stature in children, diagnosing acromegaly or gigantism, and assessing pituitary function in adults with suspected hypopituitarism.
Normal Range
The normal range for growth hormone (GH) levels in the blood can vary, but typically, a random GH level is less than 10 ng/mL. For stimulation tests, a peak GH level of at least 10-20 ng/mL is considered normal. In children, the normal range may be higher, depending on age and pubertal stage.
Low Values - Possible Causes
Possible causes of low values include: Hypopituitarism, Sheehan's syndrome, pituitary tumors or damage, radiation therapy to the brain, and genetic conditions like Prader-Willi syndrome.
High Values - Possible Causes
Possible causes of high values include: Acromegaly, gigantism, pituitary adenomas, hyperpituitarism, and certain types of hypothalamic disorders that lead to excessive GH secretion.
