Growth Hormone Stimulation Test: What Happens, Before, During & After the Test?

Before getting an hGH test done at your nearest diagnostic center, consider the following factors:

  • Don’t allow your child to eat or drink anything after midnight. 
  • No medication should be given to your child unless suggested by your doctor. 
  • If your child is on steroids, inform your healthcare provider about this.
  • In case your child has any allergies, this also should be informed to your healthcare provider.
  • Let your child get ample rest before undertaking the hGH test.

How is the Growth Hormone Test conducted? 

Read along to find out the answer here:

  • Doctors will apply a numbing cream to your child’s hand to ensure that the area has no sensation while inserting the IV.
  • The IV will be utilized throughout the therapy to draw blood and conduct other tests.
  • Drawing blood samples will continue for about 3-4 hours.

After the hGH test is conducted, offer your child food and water to recharge after a long period and consult with the healthcare expert. Since your child lost significant blood, you can also give them glucose mixed in water to avoid making them feel lazy or weak.

The same procedure applies to adults, where fasting the night before the hGH test is vital for accurate test results.

Interpreting the Growth Hormone Test  Results

Have the test results in hand but don’t know how to assess them? Before we discuss how to interpret your results, you must know the standard range of growth hormone levels (shown below):

Male (adults)

0.4-10 ng/mL

Female (adults)

1-14 ng/mL


10-50 ng/ml

You can check the hGH test results in the following ways.

  • If there is no indication of a rise in the growth hormone levels during the hGH test, this indicates deficiency.
  • Similarly, if GH levels don't decrease while a Growth Hormone Suppression test is conducted, it might indicate symptoms of gigantism in children.

This condition arises primarily when a tumor is present at the base of the pituitary gland. You can have further hGH tests conducted to figure out the intensity and size of the tumor. However, it's best to consult your healthcare professional for the best treatment plan for your overall well-being, even when you or your child has no tumor.
