When a deficiency of growth hormone is suspected, a ‘growth hormone stimulating test’ is performed using growth hormone-releasing hormone or other substances, in order to determine the ability of the pituitary gland to release growth hormone. Note: Growth hormone stimulation testing is not required in these cases. Growth hormone is released in pulses, so a single measurement of the blood level is not normally clinically useful.
