Overview
Overview
Hyperprolactinaemia (BrE) or hyperprolactinemia (AmE) is the presence of abnormally high levels of prolactin in the blood. Normal levels are less than 580 mIU/L for women, and less than 450 mIU/L for men.
The hormone prolactin is downregulated by dopamine and is upregulated by estrogen. A falsely high measurement may occur due to the presence of the biologically inactive macroprolactin in the serum. This can show up as high prolactin in some types of tests, but is asymptomatic.
