A growth hormone test is done to find out why a child is small or growing slowly. The test tells how much growth hormone a person’s body is making.
This test is used to help diagnose growth hormone deficiency. Growth hormone is needed by the body in order to grow.
There are two medicines given during this test, arginine and clonidine. Both of these medicines cause the body to release growth hormone.
During the test, nurses draw blood samples at special times to see how much growth hormone the body is making.
