Prolactin

Prolactin is a pituitary hormone that drives breast milk after childbirth. A high level outside breastfeeding can upset periods, delay pregnancy or cause nipple discharge.

Stress, exercise, poor sleep and some medicines raise it temporarily, so preparation matters.

Preparation before the test

• Give the sample 2–3 hours after waking up.
• Rest 20 minutes before the sample and avoid exercise.
• Tell your doctor about antidepressants or stomach medicines.
