Red Cell Morphology
Martha MacPherson, R.T. and Marjorie A. Spahn, MT (ASCP)
All major aspects of red cell morphology are reviewed in this richly illustrated interactive course that uses numerous photomicrographs to identify and heighten study of morphologic abnormalities in red cell size, shape, and color. This course is ideal for review by techs and students and use in continuing education and cross training.
