Growth hormone stimulation test
Growth hormone stimulation tests
Growth hormone stimulation tests are procedures used to measure the amount of growth hormone in a person’s body. These tests can be used to diagnose disorders of the pituitary gland, such as growth hormone deficiency. The growth hormone stimulation test measures the body’s response to changes in levels of growth hormone.
Preparation for the Test
Patients normally do not need to do special preparation for the test. n some cases, it may be advisable for the patient to avoid certain types of medications that may interfere with the test. Here are some of the medications that can possibly interfere with growth hormone stimulation tests:
- Diuretics
- Hormones
- Oral contraceptives
- Corticosteroids
- Propranolol
Procedure
The test begins with taking a sample of the patient’s blood. After the sample is obtained, the patient is given an injection of growth hormone releasing hormone (GHRH). Another sample of blood is taken after one hour for measurement of the growth hormone level. The level of the hormone in the second sample is compared with that in the first sample, and the differences can indicate whether the pituitary gland is functioning properly or not.
Types of Growth Hormone Stimulation Tests
- Insulin-like growth factor 1 test
- Growth hormone stimulation test
- Arginine stimulation test
- Clonidine stimulation test
- Glycopyrrolate stimulation test
- Glucagon stimulation test
Risks and Complications
Growth hormone stimulation tests are safe and generally do not cause any side effects. However, some patients may experience some minor reactions, such as dizziness, headache, nausea, and vomiting. These reactions usually go away on their own.
When to Perform a Growth Hormone Stimulation Test?
Growth hormone stimulation tests are usually performed when someone is suspected of having growth hormone deficiency. This disorder is most commonly seen in children, however it can also be seen in adults. The test can also be used to diagnose tumors or other abnormalities in the pituitary gland.
