The Prolactin test is a blood test that measures the level of prolactin, a hormone produced by the pituitary gland located at the base of the brain. Prolactin plays an important role in stimulating breast development and milk production after childbirth, while also helping regulate reproductive health, menstrual cycles, and hormone balance in both women and men.
This test is commonly recommended when a person experiences irregular menstrual cycles, infertility, unexpected breast milk production (galactorrhea), decreased libido, erectile dysfunction, headaches, vision problems, or when a doctor suspects hormonal imbalance. It helps diagnose and monitor conditions such as pituitary gland disorders, prolactinoma (a benign pituitary tumor), infertility-related hormonal issues, menstrual disorders, thyroid dysfunction, and reproductive health abnormalities. The Prolactin test is widely used in fertility evaluation, hormone assessment, and endocrine disorder diagnosis, helping doctors determine appropriate treatment and ongoing monitoring when abnormal prolactin levels are detected.
