ABPath Cytopathology

It is a one-day, computer-based exam made up of combined Written and Practical sections plus Virtual Microscopy sections. There are no glass slides; all microscopy is virtual. Every question is multiple-choice in single-best-answer format, and the items assess knowledge, judgment, and problem-solving rather than simple recall.

Per the ABPath exam description, the Written/Practical sections contain 220 questions with 4 hours 20 minutes, and the Virtual Microscopy section contains 70 questions with 3 hours 32 minutes. Together that is 290 questions. Confirm current timing on the ABPath site before your test date, since schedules can be revised.

It is a subspecialty certifying exam, so difficulty is high and the bar assumes fellowship-level competence. The practical and virtual microscopy portions reward pattern recognition and correlation with histology and clinical data, not isolated fact recall. Most candidates find timed virtual microscopy practice the most valuable preparation because locator efficiency directly affects performance.

Typically the cervical/anal cytology slides are dotted to direct attention, while FNA and non-gynecologic slides are usually not dotted. You should therefore practice systematic screening of undotted slides, since you will be responsible for locating diagnostic material yourself in those cases.

Start with gynecologic/anal cytology, which is the largest content area: Bethesda terminology, HPV testing and genotyping, immunocytochemistry, morphology of normal through malignant lesions, and current screening and management guidelines. Then move to non-gynecologic and FNA material by organ system, and finish with laboratory management, regulations, and statistics.

The exam description lists standardized reporting terminology for thyroid, salivary gland, pancreaticobiliary, breast, urinary, serous fluids, respiratory cytology, lymph node, and bone and soft tissue, along with Bethesda System terminology for cervical cytology and WHO/LAST recommendations for HPV-associated squamous lesions of the lower anogenital tract.

Expect HPV testing and genotyping, immunocytochemistry, histochemical and immunohistochemical stains, flow cytometry, and molecular, cytogenetic, and genomic testing. Ancillary studies are presented in context, including clinical presentation, radiologic findings, disease associations, prognostic significance, and companion or complementary diagnostics tied to targeted therapy.

It covers cytopathology laboratory accreditation requirements, quality assurance, safety, test validation, federal laws and agency regulations, billing and coding, statistics relevant to health care, informatics and digital pathology, physician credentialing, continuing certification, and litigation in pathology. This material is often underprepared relative to its share of the exam.

Candidates commonly lose points by neglecting laboratory management and regulatory content, by being slow at virtual microscopy navigation, and by over-relying on morphology without integrating clinical, radiologic, and histologic correlation or management guidelines. Underpreparing standardized reporting terminology for non-gynecologic sites is another frequent weakness.

Those details are not stated in the source material used for this page, so they are marked for review rather than guessed. Consult ABPath directly through its subspecialty exam descriptions, exam dates and fees pages, and Booklet of Information, and use your PATHway account for application deadlines and official notices.
