Hos patienter med isoleret GH opstået i barndommen (ingen tegn på hypothalamisk hypofysær sygdom eller kraniebestråling) anbefales 2 dynamiske tests, undtagen for patienter med lave koncentrationer af IGF- I koncentrationer (SDS < - 2), som kan vurderes ud fra en test.
In patients with childhood onset isolated GH deficiency (no evidence of hypothalamic-pituitary disease or cranial irradiation), two dynamic tests should be recommended, except for those having low IGF-I concentrations (SDS < -2) who may be considered for one test.
