Prolactin, 4 Specimens

The Prolactin, 4 Specimens test contains 1 test.

During pregnancy and postpartum lactation, serum prolactin can increase 10 to 20-fold. Exercise, stress, and sleep also cause transient increases in prolactin levels. Consistently elevated serum prolactin levels (greater than 30 ng/mL), in the absence of pregnancy and postpartum lactation, are indicative of hyperprolactinemia. Hypersecretion of prolactin can be caused by pituitary adenomas, hypothalamic disease, breast or chest wall stimulation, renal failure or hypothyroidism. A number of drugs, including many antidepressants, are also common causes of abnormally elevated prolactin levels. Hyperprolactinemia often results in galactorrhea, amenorrhea, and infertility in females, and impotence and hypogonadism in males. Renal failure, hypothyroidism, and prolactin-secreting pituitary adenomas are also common causes of abnormally elevated prolactin levels.
