Objective: Macroprolactinaemia is the phenomenon of forming immunoglobulins (Igs) against prolactin (PRL). The Ig–PRL complex has an increased half-life resulting in elevated levels of immunoreactivity in most PRL immunoassays without having any significance. Identifying macroprolactinaemia-induced hyperprolactinaemia is essential in order to prevent unnecessary testing and treatment. This study is to establish the combined intra- and inter-individual variability in macro...
