This New Short Textbook represents a considerable updating of the book's content as well as reformatting in the large page size. It includes new chapters on inborn errors of metabolism, therapeutic drug monitoring and on toxicology. And test no longer routinely used in the UK, but which are common in developing countries, are also included. Chemical pathology has now expanded very much beyond the laboratory testing of patient's specimens and has important implications in such areas as intensive care monitoring and bedside evaluation of disease. This book is aimed at the undergraduate medical students and the MRCP, FRCS candidates and it is suitable as an introductory text to those studying for MRCPath, MSc (Clinical Biochemistry). An ELBS/LPBB edition is available.
