The brain generates a prolactin hormone, which triggers milk production following childbirth to support breastfeeding. Usually, this prolactin hormone rises significantly during pregnancy and lactation.
Therefore, a prolactin blood test may be conducted for the following reasons:
- To determine the cause of milky nipple discharge.
- To monitor prolactin levels if you are taking testosterone.
- To assess prolactin levels if you have a condition linked to an increased risk of elevated levels.
- To investigate possible causes of low sex drive if you are biologically a male.
Further assessment with a healthcare professional may be necessary, depending on your test results.
How to Prepare for Your Prolactin Blood Test
- Stay hydrated by consuming plenty of water 24 hours before your test to help make the blood draw easier.
- Choose loose-fitting clothing that makes it easy to access your arms and hands.
- If you are taking anticoagulants, it’s best to take them after your test. If absolutely necessary, you may take them beforehand.
- If you’re nervous, let GP know. They will help keep you calm and ensure the process is as quick and comfortable as possible.
