This test measures the level of prolactin in the blood.

  • The pituitary gland is attached to the brain.
  • The pituitary gland helps control the level of hormones produced by several other glands in the body.

Prolactin is a hormone that is produced by the pituitary gland. The primary role of prolactin is to stimulate the production of breast milk. Increased prolactin levels can also can be seen with:

  • Anorexia nervosa (eating disorder)
  • Thyroid disease (hypothyroidism or reduced thyroid hormone production)
  • Kidney disease
  • Liver disease
  • Diseases of the pituitary gland
  • Diseases of the hypothalamus – the hypothalamus is a part of the brain that, through its influence on the pituitary gland, helps control the function of other glands in the body. It helps control sleep, temperature, hunger, thirst and mood.
  • Polycystic ovary syndrome (PCOS) – a condition that causes menstrual problems, infertility, fluid filled ovarian sacs (cysts) and other physical symptoms.

A low prolactin level can indicate a decrease in the functioning of the pituitary gland. It does not usually require treatment. However, your healthcare provider may recommend additional blood tests to make sure your other hormone levels are normal.

In an adult, the blood sample is taken by placing a needle in a vein in the arm.

  • Be sure to tell your healthcare provider about any medications you are taking.
  • Some medications can interfere with the test.

This care path's costs do not include the charge to draw blood from a vein (venipuncture). There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • What is the reason for the test? Will the test results change my treatment plan? If not, do I need the test?
