Prolactin is a hormone with several important roles in the body.
This test measures your prolactin level, a hormone commonly assessed as part of fertility, reproductive health, and wider hormone investigations.
The result provides a snapshot of your prolactin level at the time of testing and may be considered alongside other hormone markers.
You might consider this test if you’re reviewing your hormone health, exploring fertility, have been advised to check your prolactin level, or would like more information about this hormone.
- Prepare for your test by following these instructions.
- Take your sample between 6am and 10am.
- Avoid vigorous exercise or sexual activity for 48 hours beforehand – both can raise your prolactin level.
- Avoid nipple stimulation, as this can increase prolactin levels.
- Taking this test fasted is preferable but not compulsory as eating can impact prolactin levels.
- Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.

- Professional blood sample collection

Any specific instructions will be shown with your test and sent to you when you book.
It can also help to stay well hydrated before your blood draw unless your test instructions tell you otherwise.
After your blood draw, keep the plaster or dressing in place for around 30–60 minutes.
A small amount of tenderness or bruising can sometimes happen afterwards and usually settles within a few days.
Try to avoid heavy lifting with that arm for at least a few hours after your blood draw. If you notice a small bruise, a cold compress may help.
