Anti-thyroid peroxidase (TPO) antibodies – Comparative analysis of two automatic methods, ECLIA and CMIA

Abstract

Introduction: Anti-thyroid peroxidase autoantibodies (TPO) is an essential diagnostic tool for autoimmune disorders of the thyroid gland. However, TPO results are not always comparable due to differences between methods. Here, we aimed to investigate the differences between two modern laboratory methods for TPO measurement: electrochemiluminescence (ECLIA) and chemiluminescence microparticle (CMIA) immunoassays.
