Growth Hormone Profile

Why am I having this test?

Your consultant/specialist doctor/nurse has decided that it is necessary for you to undergo a series of blood tests, so we can monitor the amount of growth hormone your body is producing. This test is used to assess the effectiveness of your treatment for your Acromegaly (excess of growth hormone).

Who carries out this test?
A nurse who specialises in endocrinology is responsible for carrying out this test.

Where is the test carried out?
You will be sent a letter with details of the test and which department you will need to attend. If you wish you may bring a companion with you and they may stay with you during the test.

How long will the test take?
The test usually takes approximately 3 hours to complete. You may wish to bring a book, magazine or activity with you.

What do I need to do before the test?

• There is no special preparation required before you come for this test.
• You may eat and drink normally prior to and during the test.
• Please carry on taking any medicines that you are already on, unless we have specifically asked you not to.

What happens during the test?

• On arrival you will meet the nurse who is responsible for the test. The nurse will explain the test and you will be given the opportunity to ask questions prior to the start of the test.
• A cannula, a fine plastic tube, is placed into a vein in your arm. This is used to take blood samples. There may be some discomfort for a few seconds.
• An initial blood sample will be taken. Further samples are then taken at half hourly intervals during the course of the test for a total period of 2 hours and 30 minutes which will be 6 blood samples in total.
• Your blood pressure will be checked as appropriate during the test.
• Lunch will be provided for you, but not your companion, if required.
• At the end of the test, the cannula will be removed and a small dressing applied. The dressing may be removed when you get home.

Are there any side effects?
After the test, you may have a small bruise where the needle went in. Bruises can be painful, but are usually harmless and fade over the next few days.

What happens after the test?

• On completion of the test you will be safe to resume your normal daily activities.
• If you have been asked to stop any medicines prior to the test, the nurse will let you know when to restart the medicine.
• Based on the results of the test, your specialist doctor or nurse will be able to decide on the effectiveness of your treatment.
• The results will be discussed at your next clinic visit or a letter will be sent to you and your GP.
• The nurse looking after you will arrange a further appointment as required.
