About Prolactin Levels Blood Test in Arlington Heights
What the prolactin test measures and why it is ordered
The test quantifies prolactin in a blood sample. Because prolactin secretion follows a daily rhythm and rises with sleep, stress, exercise, and nipple stimulation, results are interpreted alongside the time of collection and the person's recent activity rather than as an isolated number.
Clinicians order prolactin testing to evaluate unexplained milk production outside of breastfeeding, absent or irregular menstrual cycles, infertility, reduced sex drive, erectile difficulties, or symptoms that suggest a pituitary problem such as persistent headaches or visual changes. It may also be used to monitor people taking medications known to raise prolactin or those with a previously identified pituitary condition.
Elevated prolactin can result from a benign pituitary tumor called a prolactinoma, certain prescription drugs, an underactive thyroid, or chronic kidney disease. Low levels are uncommon and are usually considered in the context of overall pituitary function. Because many factors influence the result, a single abnormal value often leads to a repeat measurement or additional testing before any conclusion is drawn.
