'The objective towards standardization is largely met, since world experts on each assay collaborated to evaluate and compare the available methodologies and point to the advantages and disadvantages of each one. This book is written for clinical thrombosis and hemostasis laboratorians. Another attractive feature is the degree of expertise recruited to produce these critical summaries of existing methodologies. This book is a long overdue update of the first edition in view of the multitude of newly developed methodologies and the number of manufacturers involved.' Demetra D.
