Prolactin is involved in milk production and can influence menstrual cycles and fertility. It may be measured when symptoms suggest a change.

Understanding the test
Also called Milk & Fertility Hormone
Prolactin may be checked with unexpected milk production, cycle changes or selected fertility concerns. Medicines and pregnancy are important background.
Prolactin can help evaluate changes in periods, milk production or reproductive function.
Rest, medicine history and sometimes a repeat specimen help clarify a mild increase.
Before your sample
Confirm the collection time and allow a few quiet minutes before the draw. Tell the team about recent exercise, pregnancy or breastfeeding and any medicines relevant to the referral.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

A mild elevation is often assessed again under rested conditions. Persistent changes may merit further investigation after common explanations are considered.

Patient questions
Stress, recent activity and some medicines can affect the result. A clinician may arrange a repeat sample under more consistent conditions before drawing conclusions.
Drugs that block dopamine are the main group: a number of antipsychotics, some antidepressants, and anti-sickness medicines such as metoclopramide and domperidone. Others contribute less predictably. Never stop a prescribed medication to get a better result; bring the list to your doctor and let them judge.
Prolactin dampens the pulsed signal from the hypothalamus that drives FSH and LH. Without that rhythm the ovaries do not receive the instruction to mature and release an egg, so cycles become infrequent or stop. Bringing prolactin back down usually allows cycles to return.
