Canadian Pathology Quality Assurance

Canadian Pathology Quality Assurance is a Canadian not-for-profit organization focused on improving the quality of biomarker testing in diagnostic medical laboratories. It provides external quality assurance and proficiency testing programs spanning immunohistochemistry and molecular pathology, including end-to-end molecular assessments that evaluate analytical accuracy, turnaround time, report interpretation, and reporting clarity. The organization distributes clinically validated samples and supports laboratories with biomarker optimization and validation assistance. CPQA serves laboratories in Canada and internationally and is positioned as a healthcare quality infrastructure organization rather than a therapeutic drug developer. Its work supports precision oncology by helping ensure reliable pathology and molecular test results used to guide treatment decisions.
