How is the prolactin (PRL) test done?

ANSWER

You don’t need to make any special preparations for a prolactin test. You will get a blood sample taken at a lab or a hospital. A lab worker will put a needle into a vein in your arm to take out a small amount of blood.

Some people feel just a little sting. Others might feel moderate pain and see slight bruising afterwards.

After a few days, you’ll get the results of your prolactin test in the form of a number.
