Decreased response to growth hormone stimulation test

Definitions
Insufficient responses to growth hormone (GH) provocation tests. GH deficiency is defined as a serum peak GH concentration less than 10 ng/mL on provocation with a combination of at least two separate stimulation tests. GH stimulation tests are performed with various stimuli, such as insulin, L-dopa, arginine, and growth hormone releasing hormone (GHRH). The test using insulin as a stimulus is classically recommended, but this test has potential risks such as hypoglycemia. The effects of growth hormone are mediated almost exclusively by insulin-like growth factor 1(IGF-1), which is produced primarily in the liver. Growth hormone deficiency refers to inadequate levels of GH (and therefore IGF-1), resulting in growth retardation in children and metabolic disturbances in adults.
