What is the purpose of a prolactin test?
The prolactin test is used to diagnose pituitary dysfunction that might be caused by a tumor called an adenoma. In some circumstances, the test is also used to evaluate absence of menstrual periods (amenorrhea), or spontaneous production of milk (galactorrhea) by a woman who is not pregnant or lactating.
