What is Prolactin (Prolactin)?

Prolactin is measured as part of a female hormones panel. Your prolactin is in a healthy range.

What does a high Prolactin mean?

Your prolactin is elevated. Mild rises can come from stress, recent breast exam, or medications; persistent elevation can cause irregular periods or milk production and is sometimes due to a small, benign pituitary growth. Often it should be rechecked under calm, fasting conditions.
