Numerous pharmacologic agents such as insulin-induced hypoglycemia, levodopa, arginine, arginine plus levodopa, argin-ine plus GHRH, clonidine, and glucagon have been used to stimulate the pituitary to produce GH. However, no single test perfectly predicts GH deficiency or displays 100% sensitivity and specificity. 3 Additionally, administration of each of these tests is associated with adverse effects requiring close medical supervision. Further, current abnormal cutoffs to determine diagnosis are arbitrarily defined and lack universal con-

In prepubertal children, measurement of IGF-I concentrations may be useful in evaluating GH deficiency, with 100% specificity and 70% to 90% sensitivity.34 In children, the diagnosis of GH deficiency is further supported if height is more than two standard deviations below the population mean (age- and sex-

matched). Failure of linear growth is an almost universal presenting feature of childhood GH deficiency.
