What Is a Prolactin Assay?
A prolactin assay is a simple blood test. It measures the amount of prolactin in your blood. Prolactin is a hormone made by the pituitary gland. This gland sits at the base of your brain. Doctors often use the prolactin assay to check for hormone problems. For example, it helps find out why someone has unusual symptoms like breast milk production or missed periods.
Why Is a Prolactin Assay Ordered?
Doctors order a prolactin assay for many reasons. Sometimes, it helps find the cause of certain symptoms. Other times, it checks for health conditions linked to hormone changes. For instance, if you have headaches or vision problems, your doctor may suggest this test. In addition, the prolactin blood test can help diagnose pituitary gland issues.
