Macroprolactin
Also known as Macroprolactin BloodWhat is this test?
Macroprolactin test is used to measure both prolactin and macroprolactin levels in the blood. This test does not distinguish between prolactin and macroprolactin. This test helps in the investigation of elevated levels of prolactin to make sure they are not caused by high macroprolactin.
What are prolactin and macroprolactin?
Prolactin is also known as PRL or lactogenic hormone. It is produced by the pituitary gland. Prolactin helps in the production of breast milk in women who are pregnant or breastfeeding. The exact role of prolactin in men is not known. However, small amounts of prolactin are produced in both men and women that help to measure sexual satisfaction in both men and women. Macroprolactin is bound to IgG antibodies and is, therefore inactive. The complex of prolactin which is bound to immunoglobulin is called hyperprolactinemia. This is caused by macroprolactin.
Why this test is performed?
This test may be recommended to you if your prolactin levels are high and to make sure that it is not caused by high macroprolactin. This would show no effect on fertility, milk production, or menstrual cycle.
