IGF-1 testing may be ordered, along with a GH stimulation test, when a child has symptoms of GH deficiency, such as a slowed growth rate and short stature. They also may be ordered when adults have symptoms that the doctor suspects may be due to a GH deficiency. An IGF-1 also may be ordered when a doctor suspects that a person has an underactive pituitary gland and at intervals to monitor patients on GH therapy.
