Diagnosis of acromegaly and assessment of treatment efficacy in conjunction with glucose suppression test. Diagnosis of human growth hormone deficiency in conjunction with growth hormone stimulation test.
The anterior pituitary secretes human growth hormone hGH in response to exercise, deep sleep, hypoglycemia, and protein ingestion. Hyposecretion of hGH causes dwarfism in children. Hypersecretion causes gigantism in children or acromegaly in adults. Because hGH levels in normal and diseased populations overlap, hGH suppression and stimulation tests are needed to evaluate conditions of hGH excess and deficiency; random hGH levels are inadequate.
Reference intervals have not been formally verified in-house for pediatric and adolescent patients. The published literature indicates that reference intervals for adult, pediatric, and adolescent patients are comparable.
For SI unit Reference Values, see https: Patients with acromegaly fail to show normal suppression. Using the Access ultrasensitive hGH assay, a cutoff of 0.
Low levels, particularly under stimulation, indicate human growth hormone deficiency. The test has limited value in assessing growth hormone secretion in normal children. Suspected causes of dwarfism need to be diagnosed with the aid of provocative testing. Elevated levels of human growth hormone indicate the possibility of gigantism or acromegaly, but must be confirmed with stimulation and suppression testing. Determination of nadir growth hormone concentration cutoff following oral glucose tolerance testing using the Beckman Coulter ultrasensitive growth hormone assay patients with newly diagnosed acromegaly, acromegaly in remission, and healthy subjects.
