This unique book is written by Barbara Bain, a leading haematologist with a reputation for her educational prowess in the field. It provides a concise overview of the diseases and focuses on the selection, performance, and interpretation of the results of tests that should be offered by all but the very specialist referral centers. Where more specialist tests are required, the reader is given an overview of what the specialist center will do, with guidance on what the result will imply. This book is extremely practical in orientation and it will become an essential reference volume in the general haematology laboratory.
