Human growth hormone (HGH) plays a role in growth and metabolism processes. Despite the importance of HGH in the body, there are still unfortunate people who lack the proper number of HGH in the body. The amount of HGH in the body and the capability of the pituitary gland to produce such hormone can be measured through undergoing tests.
Aside from the popular growth stimulation test (GHST), there are still other tests that can be done to determine if a person has HGH diseases. These tests are the growth hormone suppression test and the Somatomedin C test.
The growth hormone suppression test is also called the glucose loading test. This test assesses too much baseline levels of HGH and confirms analysis of acromegaly and gigantism. The patient who will undergo this kind of test should not eat or drink from midnight the night before the test and until blood samples are drawn. Physical activities of the patient should be restricted. The test procedures usually require two varied blood samples. The first blood sample is drawn before the ingestion of glucose through the mouth and the second sample is drawn after two hours of intake of glucose.
In normal patients, loading of glucose restrains the HGH production. Patients with excessive HGH levels and which HGH levels are not suppressed after glucose intake are considered to be positive of acromegaly or gigantism. Patients who have undergone the growth suppression test may experience queasiness after test but this can be easily remedied by ice chips.
