American Registry for Pathology

The American Registry for Pathology (ARP) is an organization that manages a national database of pathology specimens and associated clinical information. Its goal is to support medical research, education, and quality assurance by providing a comprehensive repository of tissue samples and data from hospitals and laboratories across the United States. Pathologists and researchers use this resource to study diseases, improve diagnostic methods, and develop new treatments. The ARP plays a vital role in advancing understanding of medical conditions through its secure and organized collection of biological specimens and related information.
