Book Review: Immunoassay of Steroids in Saliva

focus of the reader on the immediately preceding subject. The subject of each chapter is presented in a logical form, starting with an introduction to the chemical and molecular structure, where appropriate, followed by metabolism and control mechanisms; the next paragraphs cover diagnostic criteria and the role in disease. This leads into the appropriate laboratory tests and their interpretation followed by the laboratory assay methods, which are detailed in principle and step-by-step procedure, ending with normal ranges in both 'old' and S.1. units. The appendices contain all the useful numerical data that are routinely required. It is not intended to be used only as a reference book; however, the index at the end is very detailed, making it very easy to find specific points in any subject. The objective of the Editor is to provide a practical up-to-date technical book that answers not only the question 'how' but also 'why.' In the main this objective has been achieved.
