STH
(somatotropic hormone, human growth hormone, hGH, GH)
Material: | 1 ml serum from fasting blood sample. Stress can produce an increased liberation of STH and should be avoided. |
Methods: | Ligandenassays → Chemilumineszenz-Immunoassay (CLIA) | Reference range | Males: 0,02-1,23 µg/l |
Indication | Hyposomia, macrosomia, acromegaly |
Please note | Due to circadian rhythm and short half life there is considerable variation of the peripheral the STH-concentration, hence a single measurement does not give valid information. Feasible screening parameters are IGF-1 (somatomedin C) or IGFBP-3. |
