ASCP PA study guide
ASCP PA · Work through your exam, one topic at a time.
The PA credential - Pathologists' Assistant - is one of the certifications offered by the ASCP Board of Certification (ASCP BOC), the body that administers laboratory credential examinations in the United States. It appears in the BOC's credential catalog as "PA - Pathologists' Assistant" and has its own area-of-interest page alongside disciplines such as histology, cytology, and laboratory safety. The credential is aimed at individuals who assist pathologists in anatomic pathology - gross examination and dissection, specimen handling, and autopsy services - and who want a recognized professional credential in that specialty. This independent study platform is not affiliated with, endorsed by, or sponsored by the ASCP BOC; it is a third-party preparation resource. The BOC publishes its own preparation materials, including Content Guidelines & Reading Lists and Examination Readiness Resources, and those official documents are the authoritative statement of what the PA examination covers and how it is scored. Use this platform as a supplement to that official content outline, not a replacement. Topics on this exam: Surgical Pathology and Autopsy Pathology and Laboratory Operations, Safety, and Quality Management. The ASCP PA study guide has 2 sections and about 678 words.
01Surgical Pathology and Autopsy Pathology
Surgical pathology questions test whether you can move from a gross or microscopic finding to a defensible diagnosis and then to the clinical consequence. Anchor your study in: tissue handling and fixation (10% neutral buffered formalin, roughly 1 mm/hour penetration, adequate volume-to-tissue ratio), frozen section indications and limitations, margin assessment (true margin vs. artifactually inked, en face vs. perpendicular), and staging rules per AJCC.

This domain tests management of the pathology laboratory as a regulated system. Know the hierarchy of standards: CLIA '88 as the federal baseline, CAP accreditation as the practical inspection standard, and OSHA for workplace safety. Understand personnel qualification categories (director, technical supervisor, general supervisor, testing personnel) and which duties each may perform. Know quality control vs.
