Attempts to use urinary IGF-I as a diagnostic tool for IGF deficiency or excess states were abandoned when it was realized that urinary IGF-I does not correlate with serum IGF-I and does not reflect underlying GH secretion status Thus, it appears that these long-acting GHRH analogs have a moderate enhancing effect on GH secretion and its downstream biomarkers.

HGH testing and detection methods -

UF Health research scientists make medicine better every day. They discover new ways to help people by running clinical trials. When you join a clinical trial, you can get advanced medical care. Sometimes years before it's available everywhere. You can also help make medicine better for everyone else.

If you'd like to learn more about clinical trials, visit our clinical trials page. Or click one of the links below:. This research study will find out if a new growth hormone stimulation test is safe and works as well as other tests to diagnose growth hormone deficiency GHD in children.

The stimulation test will use a new growth hormone stimulating substance…. Definition The growth hormone GH stimulation test measures the ability of the body to produce GH. Alternative Names Arginine test; Arginine - GHRH test.

How the Test is Performed Blood is drawn several times. The procedure is done the following way: An IV is usually placed in a vein, most often the inside of the elbow or the back of the hand.

The site is first cleaned with germ-killing medicine antiseptic. The first sample is drawn early in the morning. Medicine is given through the vein. This medicine stimulates the pituitary gland to release GH.

Several medicines are available. The health care provider will decide which medicine is best. Additional blood samples are drawn over the next few hours. After the last sample is taken, the IV line is removed. Pressure is applied to stop any bleeding. How to Prepare for the Test DO NOT eat for 10 to 12 hours before the test.

Eating food can change the test results. Insulin-like growth factor IGF can affect your blood glucose levels. IGF may be used as a treatment for diabetes, but more research is necessary.

Children and pre-teens who are being tested for GH deficiency should be prepared for treatment with sex steroids for a few days prior to testing. Such treatment reduces the number of falsely low GH responses to stimulation.

Some healthcare practitioners will also prescribe propranolol prior to testing to reduce the number of falsely low GH responses to stimulation. Growth hormone GH testing is primarily used to help diagnose growth hormone deficiency and to help evaluate pituitary gland function, usually as a follow-up to other abnormal pituitary hormone test results.

GH testing is also used to detect excess GH and to help diagnose and monitor the treatment of acromegaly and gigantism. Therefore, testing for the suppression or stimulation of growth hormone release from the pituitary is usually done. GH suppression testing and IGF-1 testing can also be used to monitor treatment of a pituitary tumor that produces excess GH.

Tests may be ordered at regular intervals for years afterward to monitor GH production and to detect tumor recurrence. GH stimulation testing is ordered for a child with signs and symptoms of growth hormone deficiency, such as:.

Other hormone testing, such as thyroid testing , is typically done first to rule out other conditions that may cause similar symptoms. GH deficiency is rare in children and adults.

GH suppression testing is not commonly ordered but may be done when children or adults show signs and symptoms of GH excess gigantism and acromegaly. GH and IGF-1 testing may be ordered at regular intervals for many years to monitor for excess GH. GH testing for GH deficiency should not be performed until your thyroid function has been evaluated.

If you exercise vigorously and does not experience an increase in GH levels, then you may have a GH deficiency. This finding would need to be followed up with further testing. Children diagnosed with GH deficiency who have been receiving GH medications during childhood will need to be retested when they have completed growing.

If your GH levels are not significantly suppressed during a GH suppression test they stay higher than they should and you have signs and symptoms of excess GH gigantism or acromegaly and a high IGF-1 level if measured , then it is likely that you are producing too much GH.

If a mass is found on an imaging scan usually MRI , then a pituitary tumor usually benign is likely present. If you are being monitored after successful treatment of a tumor, then increases in GH may indicate a recurrence.

For example, hypothyroidism must be treated prior to testing for GH deficiency in children; otherwise, a falsely low GH result may be seen. Other tests, such as insulin-like growth factor binding protein-3 IGFBP-3 , are sometimes ordered to help evaluate GH production.

It is important to identify GH excess or deficiency as soon as possible for good outcomes. If left untreated, a child with GH deficiency will continue to have a short stature compared to peers.

Likewise, the bone growth changes associated with gigantism and acromegaly are permanent. There can be long-term complications from GH abnormalities.

Acromegaly, for instance, can cause colon polyps increasing your risk of developing colon cancer , diabetes, high blood pressure, and problems with vision. If a pituitary tumor permanently damages pituitary cells, then multiple hormone replacement therapies may be necessary. Increased bone growth may also lead to trapped nerves carpal tunnel syndrome , arthritis, and weak bones.

It should be noted that most cases of short stature are not due to GH deficiencies. They can also be related to familial traits, a variety of diseases and conditions, and to other genetic disorders.

Rarely, a person may have symptoms associated with GH deficiency but normal or elevated GH levels due to an inherited resistance to GH. In cases of GH resistance, whereas GH levels are high and IGF-1 levels are low.

Besides growth hormone deficiency GHD , children may be treated with growth hormone replacement if they have:. Growth hormone promotes muscle growth in adults, so it may be taken by some adults as a performance-enhancing drug.

Athletes may be tested for GH or IGF-1 when they are being tested for other performance-enhancing drugs. See the article on Drugs of Abuse for more on sports-related testing. Growth Hormone Blood. University of Rochester Medical Center. Accessed October Growth Hormone Stimulation Test Outpatient.

Further chapters present a detailed overview of the epigenetics and bioinformatics of GH. This collection of up-to-date investigative data and reviews is of relevance not only to scientists involved in endocrinology but also to any physician interested in growth and development.
