The Overview of the Practice of a Licensed Pathologists’ Assistant in New York State

Licensed pathologists' assistants provide services under the direction and supervision of a licensed physician who practices anatomic pathology. Services include, but are not limited to:

  • Preparing gross tissue sections for pathology analysis which includes but is not limited to cutting, staining (as required), describing gross anatomic features, dissecting and processing surgical specimens for bio-banking, histologic processing, or other analyses (e.g. frozen section); and
  • Performing human postmortem examinations which includes but is not limited to selection of tissues and fluids for further examination, external examination, dissection, and gathering and recording information for autopsy reports.

Licensed pathologists' assistants do not diagnose or provide a medical opinion. Services of a licensed pathologists' assistant must be performed in a laboratory or other site authorized under law to perform such services.
