Their work includes examining laboratory specimens, assisting with autopsies and postmortem examinations, preparing documentation, and ensuring that procedures follow established medical standards.

History of Pathologists’ Assistant Day
The development of the pathology assistant profession is closely connected to the institutional growth of pathology in the United States. A key milestone occurred in 1922 with the founding of the American Society for Clinical Pathology (ASCP) in Chicago. The organization focused on professional training, certification, and the advancement of laboratory medicine. As pathology services expanded, trained assistants began supporting certified pathologists in specimen examination, autopsy procedures, and diagnostic preparation.
A major step toward professional recognition came on April 14, 1972, with the establishment of the American Association of Pathologists’ Assistants (AAPA). The organization was created to formalize education standards, promote professional development, and support certification pathways for pathology assistants. Over time, this helped define the role as a distinct medical profession within pathology services.
