Description
Prolactin is a pituitary hormone closely linked to fertility and menstrual health, and measuring it helps investigate a range of symptoms in both men and women.
About the Prolactin Test
This test measures prolactin, a hormone produced by the pituitary gland. Raised levels can disrupt menstrual cycles, affect fertility, cause milk production unrelated to breastfeeding, and in men contribute to reduced libido. Prolactin testing is valuable for investigating these concerns and is often part of a wider hormonal or fertility assessment.
Preparation and turnaround
A venous blood sample is taken, ideally in the morning and when you are rested, as stress and recent activity can temporarily raise prolactin. Fasting is not usually required. Results are typically available within one to two working days and are best interpreted by a doctor.

When is prolactin testing useful?
It helps investigate irregular periods, fertility concerns, unexpected milk production and, in men, reduced libido.
