White Cell and Platelet Disorders: Peripheral Blood Clues to Nonneoplastic Conditions (Online CE Course)
(based on 1687 customer ratings)
This collection of informative case studies covers current topics in white cell and platelet disorders. Topics include leukemoid reactions, leukocytosis, intracellular granules, intra-cytoplasmic inclusion bodies, platelet satellitism, and more. Excellent for continuing education for clinical laboratory science professionals.

- Recognize several peripheral white cell abnormalities and list the criteria necessary to request a morphological/clinical review.
- Recognize and list the criteria by which a leukemoid reaction is differentiated from leukocytosis with a left shift.
- Describe various intracellular white blood cell inclusions and correlate them with the metabolic, genetic, and reactive conditions with which they are associated.
