Prolactin - Blood Test - In-Store only


Prolactin is produced by the pituitary gland in the brain. It’s also known as PRL or lactogenic hormone. Prolactin is mainly used to help women produce milk after childbirth.


It’s important for both male and female reproductive health. The specific function of prolactin in men is not well-known. However, prolactin levels have been used to measure sexual satisfaction in both men and women. A prolactin level test can reveal other issues caused by the hormone.

  • Why is the prolactin test done?


    Women with prolactinoma symptoms may need the test. Prolactinoma is a noncancerous tumor on the pituitary gland that produces high levels of prolactin.

    Symptoms of prolactinoma in women include:

    • unexplained headaches
    • visual impairment
    • galactorrhea, or lactation outside of childbirth or nursing
    • pain or discomfort during sex
    • abnormal growth of body and facial hair
    • abnormal acne

    The test is usually performed on people with prolactinoma to keep track of the tumor’s response to treatment.

    In addition, the prolactin test may be needed if you’re having fertilityproblems or irregular periods. The test can also rule out other pituitary gland or hypothalamus problems.


    Men may need the test if they display symptoms of prolactinoma. Symptoms of prolactinoma in men include:

    • unexplained headaches
    • visual impairment
    • reduced sex drive or fertility problems
    • erectile dysfunction
    • abnormal lack of body and facial hair

    The test may also be used to:

    • investigate testicular dysfunction or erectile dysfunction
    • rule out problems with the pituitary gland or hypothalamus
