Comment
We believe that control samples no longer exist for the 3rd IS process and most labs no longer make the distinction based on IS.

Part Description

LP14688-3   Prolactin
Prolactin is an anterior pituitary hormone encoded by the PRL gene, synthesized and secreted by lactotrope cells in the adenohypophysis. It is also produced in other tissues including the breast and the decidua. Pituitary prolactin secretion is regulated by neuroendocrine neurons in the hypothalamus, most importantly by neurosecretory dopamine neurons of the arcuate nucleus, which inhibit prolactin secretion. Prolactin levels may be checked as part of a sex hormone workup, as elevated prolactin secretion can suppress the secretion of FSH and GnRH, leading to hypogonadism, and sometimes causing erectile dysfunction in men. Prolactin measurement may also be of use in distinguishing epileptic seizures from psychogenic non-epileptic seizures, as serum prolactin level usually rises following an epileptic seizure.[Wikipedia:Prolactin] Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
