Review of Laboratory Medicine is one of Mosby's Comprehensive Review Series. It is written for the physician as an aid in studying for board examinations. The authors instruct the reader to digest certain references listed at the beginning of each major section and then to answer the questions. There are 23 chapters, covering all the major subspecialties in the laboratory, from amniotic fluid, bacteriology, and blood banking through toxicology and urinalysis. Questions are brief and specific, and answers are equally short and relevant. The questions cover principles of pathophysiology, plus facts pertaining to the performance of laboratory procedures and their interpretation. The Review of Laboratory Medicine would be a useful guide for an internist or pathologist studying for boards.
