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 also influences other hormonal systems in both women and men. A prolactin levels blood test measures how much of this hormone is circulating in the bloodstream, offering a direct look at pituitary function and helping to explain symptoms that may be linked to an imbalance.
About Prolactin Levels Blood Test in Glendora
What the prolactin test measures and why it is ordered
Prolactin is secreted by specialized cells in the anterior pituitary. Its primary function is to prepare the breasts for lactation and to sustain milk production after childbirth. Outside of pregnancy and breastfeeding, prolactin normally remains at low levels, though it can rise temporarily in response to stress, sleep, exercise, or nipple stimulation. Because prolactin interacts with other hormones, including estrogen, progesterone, and thyroid hormones, an abnormal result can point to issues that extend beyond the breast and reproductive system.
Doctors order a prolactin test for a variety of reasons. In women, it may be used to investigate irregular menstrual cycles, absent periods, unexplained breast milk production outside of breastfeeding, or difficulty conceiving. In men, elevated prolactin can contribute to reduced libido, erectile dysfunction, breast enlargement, or low sperm production. The test is also used to monitor known pituitary conditions, such as prolactinomas, and to evaluate the effect of certain medications that can raise prolactin levels.
Results are interpreted alongside a person's symptoms, medical history, and other hormone tests. A single elevated reading does not automatically confirm a disorder, since prolactin levels fluctuate naturally and can be affected by recent activity, stress, or medication. When a result is unexpectedly high, it is common to repeat the test under more controlled conditions before drawing conclusions. Imaging or additional testing may be recommended if a pituitary cause is suspected.
