About the CAMLPR Histology exam

The CAMLPR Histology exam is one of the single-field exams administered by the Canadian Alliance of Medical Laboratory Professionals Regulators (CAMLPR). The other single-field exams are Clinical Chemistry, Hematology, Clinical Microbiology, Transfusion Medicine, Cytogenetics, Molecular Diagnostics, and Cytology.

The histology exam tests your knowledge of how tissue specimens are prepared, examined, and interpreted. This includes tissue fixation, processing, embedding, sectioning, staining, special stains, immunohistochemistry, quality control, microscopy, and the use of manual and automated techniques to support disease diagnosis and patient care.
