Description
Why It’s Done:
• To evaluate abnormal milk production (galactorrhea) in women who are not breastfeeding
• To investigate infertility in both men and women, as high prolactin levels can interfere with the reproductive system
• To assess the cause of irregular menstrual cycles or absence of menstruation (amenorrhea) in women
• To check for pituitary disorders or tumors (such as prolactinomas) that might affect prolactin production
• To monitor prolactin levels in individuals being treated for pituitary tumors or other related conditions
Preparation:
• No special preparation is generally required for this test.
• The test is often done in the morning, as prolactin levels can fluctuate throughout the day.
• Avoid stress or sexual activity before the test, as these can elevate prolactin levels.
• Fasting may not be required, but follow any specific instructions from your healthcare provider.
• Inform your doctor if you are taking medications that might affect prolactin levels, such as antipsychotics, antidepressants, or birth control pills.
