Water hardness is a measure of the dissolved mineral content of water. There are two types: the general hardness (GH) and carbonate hardness (KH). When keeping freshwater fish and plants, the GH and the KH of aquarium water should match their natural habitat.
Because growth hormone is released in pulses, a single measurement of the blood level is not normally clinically useful. Therefore, testing for the suppression or stimulation of growth hormone release from the pituitary is usually done. 1  GH stimulation tests help to diagnose GH deficiency and hypopituitarism.2  For a stimulation test, a sample of blood is drawn after 10-12 hours of fasting.herefore, testing for the suppression or stimulation of growth hormone release from the pituitary is usually done. 1  GH stimulation tests help to diagnose GH deficiency and hypopituitarism.
