External Quality Control of ER, PR, and HER2 Immunohistochemistry and Continued Need for Optimization
13 Dec 2012

Breast pathology routinely employs immunohistochemistry for the classification and subsequent selection of patients for specific therapies. However, correct interpretation, is dependent on the quality of the staining produced, which can vary enormously between laboratories, and in some instanced show day-to-day variation within the same laboratory. Therefore, it is vital that laboratories not only use standardized staining procedures for ER,PR and HER2 immunohistochemistry but also optimize protocols as required.
