About Our Prolactin Test
Note: Fasting is not required for this test.
This test measures the amount of the hormone Prolactin in the blood. Prolactin is a hormone released by the pituitary gland. Prolactin is best known for stimulating breast development and enabling milk production in women.
In non-pregnant women and in men, abnormally high levels of prolactin may indicate a tumor in the pituitary gland or a pituitary disorder.
