Growth hormone stimulation test

Growth hormone stimulation test
The growth hormone stimulation test is usually performed to identify if hGH (human growth hormone) is deficient. The test is performed by administering the amino acid arginine in a vein to raise hGH levels. The test measures the ability of the pituitary to secrete growth hormone in response to the arginine. Lack of hGH can cause growth retardation in infants and children.
