Hyperprolactinemia may be caused by a complex of prolactin bound to immuno- globulin labelled as Macroprolactin. Hyperprolactinemia attributable to macroprolactin is a frequent cause of misdiagnosis and mismanagement as these patients are asymptomatic. Macroprolactin should be considered if prolactin levels are elevated, but signs and symptoms of hyperprolactinemia are absent or pituitary imaging studies are normal.
