GH supplementation is an injected medicine that contains manufactured human growth hormone. When GH deficiency is diagnosed and treated early, some children can grow several inches in the first year of treatment.

Others grow less and more slowly, but still benefit from treatment. If GH levels don't decrease to a certain level during a GH suppression test, it may mean your child has gigantism or you have acromegaly.

Gigantism and acromegaly are most often caused by a tumor in pituitary gland, a small organ in the base of the brain that controls many functions, including growth. If the disorders were not caused by a tumor, you or your child may need more tests.

Growth Hormone Tests. What are growth hormone tests? What are they used for? GH tests are used to diagnose GH disorders, including: GH deficiency.

In children, GH is essential for normal growth and development. A GH deficiency can cause a child to grow more slowly and be much shorter than children of the same age. In adults, GH deficiency can lead to low bone density and reduced muscle mass.

This is a rare childhood disorder that causes the body to produce too much GH. Children with gigantism are very tall for their age and have large hands and feet.

This disorder, which affects adults, causes the body to produce too much growth hormone. Adults with acromegaly have thicker than normal bones and enlarged hands, feet, and facial features. The tests may also be used if other tests show a problem with the pituitary gland.

Why do I need a growth hormone test? Your provider may order a GH test if you or your child has symptoms of a GH disorder. Symptoms of GH deficiency in children include: Slowed growth rate compared with children of the same age Shorter height, arms, and legs, and lower weight than children of the same age Small penis in males Delayed puberty Adults with GH deficiency may have symptoms such as fatigue and decreased bone density and muscle mass.

Symptoms of GH excess gigantism in children include: Excessive growth compared with children of the same age Overly large head Larger than normal hands and feet Mild to moderate obesity Symptoms of GH excess acromegaly in adults include: Deep, husky voice Larger than normal facial features such as lips, nose, and tongue Excessive sweating and body odor Thickening of bones Coarse, oily skin Irregular menstrual cycles in women Erectile dysfunction in men.

More blood samples will be taken over the course of about two hours. Each sample will be tested to see if GH levels have increased.

A GH suppression test is used to check for a GH excess. You or your child will drink a solution that contains water and glucose sugar. Two more blood samples will be taken within one to two hours after drinking the solution.

The blood samples will be tested to see if GH levels have decreased. Will I need to do anything to prepare for this test? Are there any risks to this test? What do the results mean?
