College of American Pathologists

The College of American Pathologists (CAP) is a professional association that serves pathologists and laboratory professionals by providing a range of services aimed at improving diagnostic quality and patient care. Its core activities include administering a laboratory accreditation program that evaluates compliance with quality standards, developing evidence‑based practice guidelines for anatomic and clinical pathology, and offering continuing medical education through conferences, online courses, and publications. CAP also operates proficiency testing schemes that enable laboratories to monitor the accuracy and reliability of their test results over time. In addition, the organization produces specialized resources such as the CAP Cancer Protocols and checklists that guide standardized reporting of pathology specimens. Through advocacy initiatives, CAP represents the interests of its members before federal agencies, state legislatures, and international bodies concerned with laboratory regulation and healthcare policy. The association’s services are utilized by hospital laboratories, independent reference labs, academic medical centers, and government facilities across the United States and in many other countries. CAP’s membership base comprises individuals and institutions engaged in pathology practice, research, and education, creating a broad network for knowledge exchange and professional development.

CAP’s distinguishing attributes stem from its deep focus on pathology and its recognized role in establishing benchmarks for laboratory quality and diagnostic accuracy. The organization’s accreditation program is widely regarded as a hallmark of excellence, helping laboratories demonstrate adherence to rigorous operational and clinical standards. CAP’s expertise is further evidenced by its creation of the Cancer Protocols, which provide a uniform framework for cancer specimen reporting and are adopted by pathology departments nationwide to support consistent data collection and cancer registry efforts. The association also maintains a comprehensive education portfolio, delivering timely updates on scientific advances, technological innovations, and best practices through its flagship publication CAP Today and various specialty resources. Structurally, CAP operates as a nonprofit, member‑governed association, overseen by an elected board of directors that sets strategic direction and fiduciary responsibility. Its headquarters is situated in the United States of America, reflecting its primary operational base while serving a global constituency. The 2023 MOVEit ransomware incident, in which CAP was impacted by a widespread exploitation of a zero‑day vulnerability, illustrates the cybersecurity challenges faced by organizations that rely on file‑transfer services, reinforcing the need for robust protective measures even within mission‑driven professional societies.
