Immunohistochemistry Topic Center

Providing Surveys and education regarding the state-of-the-art immunohistochemistry methods for diagnosis and prediction.

Resources and educational material related to immunohistochemistry.

These FAQs address issues related to validation of tests that are new to a laboratory, as well as potential responses to test performance monitoring, especially in the setting of proficiency testing and/or other external quality assessment. Additionally, hypothetical examples of process improvement assessments are provided.

CAP members have access to the International Quality Network for Pathology (IQN Path) External Quality Assessment (EQA) projects. Log in to learn more

IQN Path brings together organizations and key stakeholders involved in quality implementation of biomarker testing in pathology. The goal of the association is to improve and promote Quality Assurance (QA) in the clinical implementation of tissue-based diagnostic, predictive and prognostic biomarkers in cancer through developing best practice professional standards for External Quality Assessment (EQA) schemes in this field.
