What is the test for?
Your child has been showing more height growth than usual at this age. Sometimes this can be a sign that they are making too much growth hormone. By doing this test we can find out if this is the problem
Who will do the test?
The test is carried out on the Children’s Day Care Unit by a trained nurse.
Do I need to do anything before the test?
Your child should eat and drink a normal carbohydrate diet for at least three days leading up to the test and undertake normal daily activities.
Your child will not be able eat anything overnight prior to attending the test, but they are able to drink small amounts of plain water.
Your child should not undertake any physical exercise on the morning of the test or during the test.
What happens during the test?
- On arrival at the Day Care Unit, local anaesthetic (magic) cream will be applied to the hands and inner elbows as we will need to insert a cannula (a very fine plastic tube that sits in the vein) to allow us to take several samples of blood.
- When the cannula has been placed, a blood sample will be taken and your child will then be given a sugary solution to drink.
- For the next 2 hours blood samples will be taken regularly, through the cannula; following the last sample the cannula will be removed.
- You will then be able to take your child home.
Are there any side-effects?
Your child may feel nauseous and dizzy during the test. This is quite common and temporary, but they will be monitored throughout.
When will I get the results of the test?
The results of the test will be discussed with you by the doctor, either by letter or in clinic. Please do not contact the secretary or Day Care Unit for the results as they are not allowed to give out this information. All urgent results will be communicated to you as soon as possible.
