About the CAMLPR Hematology exam

The CAMLPR Hematology 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, Clinical Microbiology, Transfusion Medicine, Histology, Cytogenetics, Molecular Diagnostics, and Cytology.

The Hematology exam tests your knowledge of the principles, methods, and interpretation of analyzing the cellular and non-cellular components of blood, as well as hemostasis and coagulation processes. This includes testing such as complete blood counts (CBC), peripheral blood smear evaluation, manual and automated cell counting, flow cytometry, coagulation studies, slide preparation and staining, and the use of microscopic and automated techniques to diagnose disease and monitor treatment.
