Measure your prolactin level for insights into your reproductive health and more.

This blood prolactin test measures the level of prolactin, a hormone produced by the pituitary gland. Prolactin plays a role in many bodily functions for both men and women, including milk production, breast development, sperm production and more. Testing prolactin levels can help you and your healthcare provider evaluate symptoms and conditions related to an elevated prolactin level.

Note: This test does not diagnose or determine the cause of infertility, menstrual irregularities or any health condition. People who are lactating or breastfeeding will have varied prolactin levels and should discuss this test with their healthcare provider.   It is recommended to consult with a healthcare provider if you have any questions about your result.
