Prolactin is a polypeptide hormone secreted by the lactotrophic cells of the anterior pituitary gland and has a wide range of biological effects in the human body. Accurate measurements of prolactin concentration are essential in obtaining biochemical data to support clinical decisions in the diagnosis, treatment and prevention of diseases of the pituitary gland, reproductive, immune and other body systems. The aim of our study is to carry out a comparative analysis of the serum prolactin measurement determined by the two analytical platforms Vitros ECi 3600 (Ortho-Clinical Diagnostics) and Cobas 6000 (Roche). Serum samples from 664 patients undergoing examination at the Endocrinology Research Center were included in the study. Comparative analysis of serum prolactin measurement showed that results obtained by the two analytical systems are consistent with each other (r = 0.89, p<0,05). Clinically accuracy of prolactin measurement and to a large extent using the same method is of particular importance in primary diagnosis, treatment and long-term follow-up of the patient.
