Automatic blood film preparation by rheologically controlled spinning.
During the past six years at the Biomedical Technical Center of Corning Glass Works, extensive studies on blood film preparation have resulted in a method and an instrument which offer the hematology laboratory better quality than that routinely attainable with the conventional wedge or cover-slip techniques. This spinning method provides the operator with a uniform blood "film" whose cell type distribution accurately reflects the distribution of the original liquid blood sample instead of a "smear." This film improves the accuracy of white blood cell differential counts performed manually; it also enhances the accuracy of recently developed machines which automatically locate and classify leukocytes.
