As the title suggests, this resource offers the broad perspective necessary for understanding current methods of blood component preparation. In one compact volume, topics range from history to related quality systems, from manual to automated processes, and from technical to clinical considerations--taking the subject well beyond the laboratory while complementing other procedure-based methods manuals. Comparisons of the different approaches used and their related component characteristics point up the special requirements of different recipient populations. Chapters discuss not only specific processes but also rationale, published experience, and research. An international panel of authors presents the "state-of-the-science" and includes selected European practices and perspectives to supplement those common in North America.
