| Test Name: |
GLUCAGON STIMULATION TEST - (S)
Test Code:
GLGN
|
||||
| Clinical Information: |
Growth hormone stimulation test cut-off values are assay dependent and somewhat arbitrary. An inadequate response to at least two stimulation tests, along with auxologic data and clinical assessment consistent with growth hormone deficiency are required to confirm a diagnosis.
Some laboratories recommend a peak value of > 10 ug/L for pediatric patients and suggest values of 5 – 10 ug/L are indeterminate. Values < 5 ug/L are generally considered subnormal. Method of Analysis: Chemiluminescence immunometric immunoassay |
