Prolactin Profile

Why am I having this test?

• This test is used to assess the amount of prolactin, hormone, your body is producing. Prolactin levels can be affected by many things in the body, such as certain medication, hormones, sleep, stress or pregnancy.
• If your prolactin levels are very high this may cause milk production from the breasts.
• Your consultant, specialist doctor or nurse has recommended that it is necessary for you to undergo a series of blood tests, so we can monitor the amount of prolactin your body is producing.

Who carries out this test?
A nurse who specialises in endocrinology is responsible for carrying out this test.
