Hello

Prolactin Level (PRL)

Prolactin Level (PRL)

Prolactin is a hormone produced by the anterior portion of the pituitary gland, a grape-sized organ found at the base of the brain. Normally present in low amounts in men and non-pregnant women, prolactin’s primary role is to promote lactation (breast milk production). This test measures the amount of prolactin in the blood.

prolactin level is usually high throughoutpregnancy and just after childbirth. During pregnancy, the hormones prolactin, estrogen, and progesterone stimulate breast milk development.

Sample :

No test preparation is needed, but the sample is typically collected 3 to 4 hours after waking.

clinical significance:

Prolactin is a hormone produced by the pituitary gland and its primary role is to help initiate and maintain breast milk production in pregnant and nursing women.

Prolactin testing may be used, along with other hormone tests, to help:

• Determine the cause of breast milk production not associated with pregnancy or breast-feeding
• Diagnose the cause of infertility and erectile dysfunction in men
• Diagnose the cause of menstrual irregularities and/or infertility in women
• Detect and diagnose tumors that produce excess prolactin (prolactinomas), monitor their treatment, and detect recurrences
• Evaluate anterior pituitary function or other pituitary disorder
