Is prolactin elevated in pregnancy?

Prolactin is a hormone made by the pituitary gland, a small gland at the base of the brain. Prolactin causes the breasts to grow and make milk during pregnancy and after birth.

What is considered high prolactin?

Simple blood tests to measure the amount of prolactin in the blood can confirm a diagnosis of elevated prolactin levels. Prolactin levels above 25 ng/mL, in women who are not pregnant, are considered elevated.
