Test duration
Your appointment will last approximately xxx hours.
It will take place in the Kingston Hospital Main Outpatients Department, Level 4, Corridor E, Diabetes Day Unit.
Important
This test is not suitable for women currently using hormonal contraception (for example, the oral contraceptive pill, depo injection, or contraceptive implants).
If this applies to you, get in touch with us (see Contacts below) by phone or email.
For women with a normal menstrual cycle, we need to conduct the test during days 3 to 7 of your cycle (the follicular phase). During this time, we can observe greater responses to the test.
Preparing for your test
You do not need to fast (avoid food and drink) in preparation. You can eat and drink as usual before this test.
Bring something with you to read or listen to during waiting periods between blood samples.
During the test
You can expect the following during your test.
- We will ask you to lie on a bed while we insert a small plastic tube (a cannula) into a vein in your arm. This allows us to take blood samples.
- After we have taken the first blood sample, we will give you an injection of gonadotropin-releasing hormone (GnRH) via the cannula.
- We will take further blood samples at 30 and 60 minutes following the injection.
- Once we have collected all the necessary blood samples, we will remove the cannula and the test will be complete.
