Overview of Prolactin Test

What is Prolactin Test?

The prolactin test is done to measure the levels of prolactin in the blood to check and monitor the associated disease condition. Prolactin is a hormone produced by the pituitary gland which is situated at the base of the brain. Prolactin is normally produced in both males and non-pregnant females in small amounts. The main function of this hormone is to stimulate milk production (lactation) after the childbirth, so, it is also known as the milk-producing hormone. The levels of prolactin hormone are generally high during pregnancy and after childbirth. But, high levels of prolactin can also be seen in many disease conditions in both men and women.

Sample Type

The sample type collected for Prolactin Test is: Blood

Preparation for Prolactin Test

  • Blood sample should be collected 4 hours after waking.

Why Get Tested for Prolactin Test?

  • To investigate the cause of abnormal breast milk discharge (galactorrhea), menstrual irregularities or infertility in non-pregnant women

  • To evaluate the role of prolactin in case of lactation failure in women after childbirth

  • To investigate the cause of erection problems, testicular failure or abnormal breast discharge in men

  • To investigate the cause of loss of sex drive (libido) in both men and women

  • To detect and monitor the progress of prolactinoma (tumor of the pituitary gland that causes high levels of prolactin) in both men and women


Understand more about Prolactin Test

The prolactin hormone is produced by the pituitary gland which is located at the base of the brain. The primary function of this hormone is to help in lactation i.e. production of milk after childbirth. Prolactin levels are usually high during pregnancy and after childbirth. During pregnancy, this hormone along with other hormones like estrogen and progesterone stimulates the breasts for milk production. After the childbirth, it helps to maintain the breast milk production. Suckling of the breasts by the baby is important for the release of prolactin hormone. If a woman stops breastfeeding, the level of prolactin hormone will return to normal.

Abnormally high levels of prolactin are seen in certain disease conditions like prolactinoma (non-cancerous tumor of the pituitary gland) in men and women. It is generally benign (non-cancerous) in nature and is seen more commonly in women. If the tumor is quite large, it can put pressure on the optic nerve and the patient may present with headache and visual disturbances.
