This session will focus on the pros and cons related to the practical aspects of the laboratory diagnosis of malaria [mandatory STAT testing; differences between immunologically naive and endemic area patients, including anticipated patient presentations and parasitemias; importance and clinical relevance of parasitemia result interpretations; blood collection, possible need for multiple draws, finger stick vs. venipuncture options, blood film processing, examination recommendations (including rapid and molecular methods), and reporting; and QC/method options and requirements]. There will be extensive discussions and examples of the morphology of the five human species of malaria, as well as potential identification problems and artifact issues (Plasmodium vivax, P. ovale, P. malariae, P. falciparum, and P. knowlesi). Result reporting and the clinical/therapeutic importance of report comments will also be included and emphasized. While malaria is no longer endemic within the United States, mosquito vectors are present and occasional transmission occurs within the U.S. The potential problems associated with the diagnosis of malaria in travelers will be discussed, including the failure to understand and use recommended methods for the laboratory diagnosis. A complete understanding of the clinical relevance of these issues will help ensure appropriate and adequate patient care is implemented.
After attending this session, participants will be able to:
· Discuss the STAT nature of all blood parasite testing requests (collection, processing, examination, reporting).
· Explain the differences between immunologically naive and endemic area patients, expected parasitemia results, and differences in disease presentation.
· Describe the key morphological features related to the five species of human malaria.
· Describe the pros and cons of thick and thin blood films, staining options, and quality control requirements for processing and reporting, and the recommended use of possible report comments.
Who should attend? Practicing Pathologists, Residents, Doctoral Scientists, Pathologists' Assistants, Laboratory Managers, Bench Supervisors, Bench Technologists & Technicians, Cytotechnologists, Phlebotomists, Students
