What is a Pathologists’ Assistant (PA)?
A Pathologists’ Assistant is a skilled healthcare professional with academic and practical training who provides essential services under the guidance and supervision of a pathologist. Similar to how Physician Associates collaborate with physicians, Pathologists’ Assistants collaborate with pathologists to examine cells, tissues, and organs for various diseases and diagnoses, with a focus on macroscopic evaluation, description, and sample selection. Although most Pathologists’ Assistants work primarily in Surgical Pathology (the examination of tissue removed during surgery), opportunities for Pathologists’ Assistants are broad and expanding, with Pathologists’ Assistants working in autopsy, forensics, laboratory management, informatics, biobanking, education, and more.
The training of Pathologists’ Assistants allows them to contribute to the overall efficiency of a pathology laboratory and extend the eyes, ears, and hands of the pathologist. They play a crucial role in the medical field, contributing to the diagnosis of diseases through the preparation, processing, and examination of tissue specimens. Their work involves performing gross examinations, assisting with autopsies, and ensuring the smooth operation of pathology laboratories. With their specialized skills, Pathologists’ Assistants significantly impact patient care and medical research without direct patient interaction.
