Growth hormone suppression test

Normal values:

Normal test results would reveal an hGH level of less than 3 ng/ml. In children, if the second blood sample is taken after the second hour, there may be increased levels from a rebound phenomenon die to the occurrence of reactive hypoglycemia.

What abnormal results mean:

If the hGH levels are unaltered and remain high during the suppression test, then gigantism or acromegaly is suspected. The test may need to be confirmed by retesting at the same time, under the same conditions another day.
