The Royal College of Pathologists of Australasia Quality Assurance Program (RCPAQAP) Anatomical Pathology provides a comprehensive External Quality Assurance (EQA) exercise to review the reporting of immunohistochemistry (IHC) and in-situ hybridization (ISH) breast markers through an audit of clinical results. The aim of this exercise was to provide information regarding the quality of breast marker testing within clinical laboratories from 2005 to 2015. This comprehensive audit included estrogen, progesterone, and HER2 marker reporting. This was an important quality assurance activity established in response to ongoing difficulties experienced in laboratories in this area of testing.
