A prolactin test measures both prolactin and macroprolactin levels in the blood and does not distinguish between them. Macroprolactin is bound to IgG antibodies and is therefore biologically inactive. This test is used to investigate elevated levels of prolactin to ensure that they are not caused by high macroprolactin (which would have no impact on fertility, milk production or the menstrual cycle) Macroproprolactin is estimated to be responsible for around 15% of all elevated prolactin cases.
