Investigating and Testing for Human Growth Hormone Deficiency

Growth hormone plays an important role in the growth, development and metabolism of the human body. Release of the hormone is triggered by certain factors such as, exercise, sleep, diet and depression.

The normal levels of this hormone are adequate to carry out metabolic functions of the body. However, high or low levels of HGH may result in physical and biochemical abnormalities in the body.

Insulin-like growth factor-1 affects every cell in the human body - muscle, nerve, cartilage, bone, liver, kidney, skin and lungs. It influences the growth and development of cells, mostly nerve cells, and helps in the formation of DNA in the cell. It has been found that the levels of both hormones are interrelated to each other. If we can test the levels of IGF-1, the levels of growth hormone can be assessed and monitored.

The reason why one needs to do testing, is to check whether the symptoms of the disorder are due to hormone deficiency or not. Testing is also important to assess the results of the growth hormone therapy and to observe the development in the patient.

To get accurate results in the testing, the patient is asked to stay without moving for about 1 hour, before the test is performed. This is to ensure that the hormone released is not influenced by any physical activity.

The usage of certain medications like estrogens, birth control drugs and corticosteroids also are temporarily stopped before the testing, to check their effect on the natural production of the growth hormone.

A few blood samples are taken on various days, as the levels keep changing every day. IGF-1 levels also must be tested simultaneously, since, its level changes slowly. Before the blood sample is collected the medical professional should be informed about any medications you have been taking or any disorder you have been suffering from.

Results vary from one laboratory to the other. The normal level of this hormone is about 5 ng/ ml in men, 10 ng/ ml in women and 16 ng/ ml in children. The test result for adults shows the hormone in the range of 42-110 ng/ ml.

Normal range of HGH 0 to 8 years of age 9 to 10 year of age 11 to 13 years of age
Girls 7 to 110 ng/ ml 39 to 186 ng/ ml 66 to 215 ng/ ml
Boys 4 to 87ng/ ml 26 to 98 ng/ ml 44 to 207 ng/ ml
