This 12th edition of "Clinical Diagnosis by Laboratory Methods" contains essentially the same material as the 11th edition, with certain minor changes and revisions to bring it up to date.
As usual, it is a complete reference for all laboratory work. There are numerous illustrations, many of them colored, and numerous tables. All in all, it is an excellent useful reference book for the laboratory. Old friends will receive the new edition with enthusiasm, and new users of this well-established text will find it completely satisfactory.
