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 how much of this hormone is circulating in the bloodstream at the time of collection.
About Prolactin Levels Blood Test in Downey
The prolactin levels blood test is a straightforward immunoassay performed on a blood sample, typically drawn from a vein in the arm.
Prolactin is secreted by lactotroph cells in the anterior pituitary gland. Its primary recognized function is to support lactation, but it also influences reproductive function, mood, and bone metabolism. Because prolactin release follows a daily rhythm and rises with sleep, stress, and physical activity, the timing of the blood draw and the conditions before collection can affect the result.
Clinicians order a prolactin measurement when there are signs or symptoms that suggest elevated prolactin, such as unexplained nipple discharge, irregular or absent menstrual periods, reduced libido, erectile dysfunction, or infertility. It may also be checked when imaging or other findings point to a pituitary abnormality. Low prolactin is uncommon and is usually only meaningful in specific clinical contexts.
Results are reported as a concentration, most often in nanograms per milliliter. Reference ranges vary by laboratory and by sex, and a single elevated value does not by itself establish a diagnosis. Mild elevations are frequently caused by temporary factors, so a repeat measurement or additional testing is often used to confirm a persistent pattern before further evaluation.
