A prolactin levels blood test measures the amount of prolactin, a hormone made by the pituitary gland. It is ordered to evaluate irregular menstrual periods, nipple discharge, breast milk production when not breastfeeding, or fertility problems.

What it measures

  • Prolactin — The main hormone measured; high levels can affect reproduction and milk production.
  • Thyroid-stimulating hormone (TSH) — Sometimes checked because an underactive thyroid can raise prolactin.
  • Estradiol — A form of estrogen that helps show if high prolactin is affecting ovarian function.
  • Testosterone — Measured in men because high prolactin can lower testosterone.

Who it is for

A doctor may order this test if you have symptoms such as unexplained nipple discharge, missed or irregular periods, trouble getting pregnant, or low sex drive. It is also used to monitor known pituitary conditions.

Preparation

No fasting is usually required. Tell your healthcare provider about all medicines and if you are stressed or recently exercised, as these can affect results.

Results and what they mean

Results are reported as a number with a reference range, which varies by lab and by whether you are pregnant or breastfeeding. A clinician interprets the result along with your symptoms and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
