An addition to the “Current Clinical Pathology” series, the 344-page volume Flow Cytometry in Hematopathology: A Visual Approach to Data Analysis and Interpretation, Second Edition, reflects recent advances in the flow cytometry analysis of hematopoietic disorders. The chapters have been revised to incorporate new text and figures. The first chapter discusses factors that have contributed to the progress of the analytical technique, including the expanding variety of available monoclonal antibodies and fluorochromes. Other sections address flow cytometry immunophenotyping and DNA analysis, and flow cytometry data analysis on nearly homogeneous samples and on heterogeneous specimens. A compact disc containing case studies is included. Drs. Doyen Nguyen, Lawrence W. Diamond and Raul C. Braylan; Humana Press, Totowa, N.J., 2007; $139, hardcover, e-book.
