An ACTH stimulation test is done to determine if the adrenal glands − located on top of each kidney − are able to make the right amount of hormones called cortisol and aldosterone. These hormones help keep blood pressure and blood sugar normal, as well as maintain salt and water balance in the body.
The ACTH stim test is done by giving a medication called Cortrosyn and drawing blood levels of cortisol. Cortrosyn stimulates cortisol production. Cortrosyn is given in two different doses. The test may be called low-dose or high-dose depending on what your doctor orders.
Show AllThere are no dietary restrictions with the ACTH stimulation test. It would best if the child wears a short-sleeved shirt to the test. A low-dose stim test can be done any time of the day. This test takes about 20 minutes.
A high-dose stim test must be done in the morning. This test takes about an hour.
Explain what will happen to your child in simple terms that the child can understand.
The test will take place in the Endocrinology Outpatient Clinic. When you arrive to clinic, your child's height and weight will be measured. Then you will go into a patient room where the IV (intravenous) catheter will be placed. This will be used to give the Cortrosyn medication and to draw the blood samples. The IV placement may be a little uncomfortable, but it is done quickly.
When the test is complete, the IV catheter will be removed. The child will be awake throughout the test. Parents may stay with the child throughout the test.
After the testing is completed, you will be discharged home. Test results will be available 1-2 weeks after testing is completed. The endocrinologist will notify you of the test results.
There are no dietary restrictions or activity limitations following the ACTH stim test.
Call your child's doctor if you have medical concerns about your child's condition.
