Normal test results show a GH level of less than 1 ng/mL. In children, the levels may be increased due to reactive hypoglycemia.

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.

If the GH levels are not changed and stay high during the suppression test, then the health care provider will suspect gigantism or acromegaly. You may need to be retested at the same time and under the same conditions on another day to confirm the test results.
