Prolactin
What Does This Test Check?
The Prolactin Blood Test measures prolactin, the hormone that supports milk production and helps regulate reproduction. An abnormally high level may affect periods, fertility or libido, which is often why this marker gets checked.
Medichecks provides the Prolactin Blood Test for 45 pounds as a home test. As a focused single-hormone check it sits in the mid-range for price on this type of test.
A raised prolactin may indicate a benign growth on the pituitary or can be pushed up by stress, medication or recent breast stimulation, so it is not a diagnosis on its own. Levels also depend on when you test, so your GP should interpret the number before any treatment is considered.
