This book will present the important aspects of clinical chemistry in the 'Made Easy' format for the senior clinical medical student or junior doctor on the ward. The book explains the rationale underlying the most common clinical chemistry tests to request and gives guidance as to what action is required on receipt of abnormal results. The text will include brief background to the underlying physiological processes involved, important differential diagnoses and further steps required in the clinical setting. The ultimate aim is to make the reader think carefully as to what clinical chemistry tests are required in different contexts and to ensure that they are equipped to deal responsibly with the result. This will result in improved clinical practice.
