ABPath Anatomic Pathology study guide
ABPath Anatomic Pathology · Work through your exam, one topic at a time.
The Anatomic Pathology Primary Certification is one of the credentialing pathways offered by the American Board of Pathology (ABPath), the body that certifies physicians who have completed accredited pathology training in the United States. This page is an independent study resource built for candidates preparing for the anatomic pathology primary examination; it is not affiliated with, endorsed by, or operated by ABPath, and it does not replace the official Booklet of Information, exam blueprint, or content specifications. The ABPath Anatomic Pathology study guide has 5 sections and about 1,421 words.
01Surgical Pathology: Specimen-Driven Reasoning and Honest Reporting
Surgical pathology questions test a disciplined sequence: confirm identity, site, and laterality; orient and ink; measure and describe; sample the tumor–normal interface; then integrate histology with stage and ancillary results. Know the CAP cancer protocols and AJCC/UICC TNM conventions, including pT and pN definitions, the y (post-treatment) and r (recurrence) prefixes, and the difference between clinical and pathologic stage.
301 words, about 2 min02Cytopathology: Adequacy, Categories, and the Two-Error Model
Cytology questions rest on two ideas: adequacy and risk stratification. Learn the reporting systems by name and structure-Bethesda cervical (NILM, ASC-US, LSIL, ASC-H, HSIL, AGC, SCC, AIS), Bethesda thyroid (categories I–VI), Milan for salivary gland, and Paris for urine (negative, AUC, SHGUC, HGUC).
302 words, about 2 min03Autopsy Pathology: Cause, Mechanism, and Manner
Autopsy questions test a triad and a process. Cause of death is the disease or injury that initiated the lethal sequence; mechanism is the physiologic derangement (arrhythmia, hemorrhage, sepsis); manner is natural, accident, homicide, suicide, or undetermined.
283 words, about 1 min04Ancillary Techniques: Panels, Controls, and Preanalytical Reality
Ancillary studies require pattern recognition plus respect for assay limits. For immunohistochemistry, understand antigen retrieval, clone selection, expected subcellular localization (nuclear, cytoplasmic, membranous), and the role of internal and external controls.
266 words, about 1 min05Laboratory Management and Informatics: Quality Systems and the Wired Laboratory
Management and informatics questions reward systems thinking. Know CLIA '88 and CAP accreditation requirements, the distinction between validation (establishing performance of a laboratory-developed test) and verification (confirming performance of an FDA-cleared test in your own setting), proficiency testing, competency assessment, and document control.
