Order Prolactin Levels Blood TestProlactin is a hormone produced by the pituitary gland, a small structure at the base of the brain. While 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 the concentration of this hormone in the bloodstream, giving clinicians a direct view of pituitary output and helping to evaluate symptoms that may point to an underlying endocrine issue.
About Prolactin Levels Blood Test in Arcadia
Prolactin testing is typically ordered when a clinician suspects that prolactin production is higher or lower than expected.
Prolactin is secreted by specialized cells in the anterior pituitary called lactotrophs. Its primary recognized function is to stimulate breast development and enable milk production after childbirth. However, prolactin also influences reproductive function, and its levels are normally kept within a narrow range by dopamine, a brain chemical that suppresses prolactin release. When that regulatory balance shifts, prolactin levels can rise or fall outside the typical range.
Elevated prolactin, a condition known as hyperprolactinemia, can occur for several reasons. The most common cause is a benign pituitary tumor called a prolactinoma, which produces excess prolactin. Other causes include certain medications, hypothyroidism, chronic kidney disease, and compression of the pituitary stalk. In women, high prolactin may lead to irregular menstrual cycles, absent periods, or milk production unrelated to breastfeeding. In men, it can cause reduced libido, erectile dysfunction, or breast enlargement.
Low prolactin is less common and is usually linked to pituitary dysfunction, such as hypopituitarism, where the pituitary gland does not produce adequate amounts of one or more hormones. Because prolactin interacts with other hormones, results are often interpreted alongside tests for thyroid function, reproductive hormones, and sometimes imaging studies. A single measurement may be repeated or performed under specific conditions, since prolactin levels can fluctuate with stress, sleep, exercise, and nipple stimulation.
