hGH ELISA Kit (Human Growth Hormone)


hGH ELISA kit is a reliable quantitative procedure for measuring human growth hormone, (hGH, human GH) in serum and plasma. This assay has a minimum sensitivity detection limit of 0.2 µIU/ml.


Growth hormone (GH) is a polypeptide hormone with a molecular weight 21,500 Da. It is produced by the acidophil cells of the anterior pituitary and is responsible for stimulating growth and cell reproduction in humans and other vertebrate animals. It is released into the bloodstream from the pituitary in a pulsatile manner under the regulatory control of GH-releasing factor (GHRF) and hypothalamic somatostatin (SS). There are many stimulators of GH secretion which include exercise, fasting, stress, dietary protein, deep sleep, estradiol and hypoglycaemia.

One of the main physiological functions of hGH is to act on the liver and other tissues in order to produce somatomedins, this is able to in turn induce growth by direct action on the target tissues.

The measurement of serum can be useful for:
(a). Index of pituitary function when hypopituitarism is suspected.
(b). Determination and treatment of growth retardation, hyposecretion is one of the various causes that can lead to small stature in children. Measuring serum concentrations, especially after a provocative stimulus (absence of response), is an important way to establish the diagnosis of this condition.
(c). Diagnosing and treating gigantism and acromegaly, especially after provocative inhibitory test (absence of response), can be used to establish the diagnosis of hypersecretion which can be due to acidophilic pituitary tumour. This is known to cause gigantism in children and acromegaly in adults, it is also possible to treat both of these disorders by either surgery or radiation.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
