Order Prolactin Levels Blood TestProlactin is a hormone produced by the pituitary gland, a small structure at the base of the brain. Although it is best known for its role in breast development and milk production, prolactin participates in a broader set of regulatory functions in both women and men. A prolactin levels blood test measures how much of this hormone is circulating in the bloodstream at the time of collection.
About Prolactin Levels Blood Test in Laurel
The prolactin levels blood test is a laboratory measurement of circulating prolactin, used to evaluate pituitary function and investigate symptoms that may relate to elevated or reduced hormone levels.
Prolactin is secreted by lactotroph cells in the anterior pituitary. Its primary recognized function is to support mammary gland development and enable milk production after childbirth. The hormone is also present in men and in women who are not lactating, where it plays roles in reproductive and metabolic regulation.
Because prolactin release is controlled by dopamine from the hypothalamus, which acts as an inhibitory signal, disruptions anywhere along that pathway can raise blood prolactin. Common categories of causes include pituitary adenomas that secrete prolactin, medications that interfere with dopamine signaling, hypothyroidism, and certain chronic conditions. Levels can also rise transiently with stress, sleep, exercise, or nipple stimulation.
A prolactin levels blood test is typically ordered when a clinician is evaluating unexplained milk production outside of breastfeeding, irregular or absent menstrual cycles, infertility, low libido, erectile dysfunction, or symptoms suggesting a pituitary mass such as headaches or visual changes. Results are interpreted alongside the patient's history, medication list, and other hormone tests, and repeat measurement is often used to confirm persistent elevation.
