text: Thus, when serum prolactin is raised, it is recommended that laboratories screen for macroprolactinaemia in order to differentiate between those patients with elevated concentrations of bioactive monomeric prolactin (true hyperprolactinaemia) and those whose hyperprolactinaemia is due to the presence of macroprolactin.12,13,17 Gel filtration chromatography (GFC), the gold standard for the measurement of serum monomeric prolactin,5 is slow, costly and labour intensive and therefore impractical for routine clinical use.
