Introduction to Bone Marrow (Online CEU Course)
John R. Snyder, Ph.D., MT(ASCP), S.H.; Marjorie A. Spahn, MT(ASCP)
This introductory course about bone marrow examination includes basics of specimen collection, specimen preparation, cellularity, evaluation of iron smears, Romanowsky stained smears, and how to perform a differential count. Unusual cells such as sea blue histocytes, flame cells, and Gaucher cells are covered. This course is a great introduction to cross train medical technologists prior to assisting physicians with marrow preparation and counting. It would also be appropriate for clinical laboratory science students.
